Use special strips of paper known as pH paper for very broad measurements of pH. pH paper can be bought for acidic neutral and alkaline compounds. Once dipped into the hair product, the paper changes color depending on the pH of the product. Then the color can be matched to a key (included with the pH paper) to determine the approximate pH.

Use a digital pH meter for more precise measurements. Though the specifics of using a pH meter will vary according to the model, the basics are the same.

Wash the electrode. The electrode is usually encased in a glass tube and can be washed by squirting it with distilled water.

Prepare the machine for calibration. This can be done by pressing the "cal" button on the machine and then immersing the electrode in one of the calibration solutions provided with the machine. These solutions are generally supplied at pH levels of 4, 7 and 10, and are in specially prepared bottles. The pH meter must be calibrated in two different solutions, but it doesn't matter which two are used.

Continue with the calibration. After pressing the "Cal" button, immerse the electrode in one calibration solution. Once the readout on the digital screen stabilizes, press the button marked "OK." Repeat this using a different solution (for example, calibrate first with the pH 7 solution, then calibrate again with the pH 10 solution).

Wash the electrode with distilled water and then repeat Step 4 with a calibration solution of a different pH.

Body Maintenance of Normal Ph

...2. Body Maintenance Of Normal pH In order to maintain a proper pH in the bodily fluids, and so that acidosis or alkalosis will not manifest, three major physiological control systems exist within the body. The first mechanism involves a buffer system for the hydrogen ion fluctuations. All bodily fluids are supplied with acid-base buffers which combine with any acid or alkaline substance and prevent excessive change in the hydrogen ion concentration. Another mechanism the body uses to maintain normal pH is within the respiratory system. When the hydrogen ion concentration (H + ) changes measurably, the respiratory system is immediately stimulated to alter the rate of pulminary ventilation. This brings about a change in the quantity of carbon dioxide (CO2) within the system. High levels of carbon dioxide in the system, as created when holding the breath or due to physiological impairments of respiration, increase the acidity of the bloodstream. Any disease that interferes with normal breathing, such as emphysema or asthma, will impede the release of CO2 from the lungs and, subsequently, this CO2 will combine with water to form carbonic acid. This increases the concentration of hydrogen ions, and thus the acidity of the blood is simultaneously increased. The last of the three major physiological control systems of the body to maintain normal pH involves the kidneys. When the (H + ) (hydrogen concentration) deviates from a normal value, the kidneys excrete either an acid or......

Rose Petals Ph Indicators Strip

...Rose Petal pH Indicator Strip II – Proponents Jhed Angelo Nemuel Parcon Princess Hope Delos Reyes Jalel Pasbal Maureen Suganob Nel Joshua Turaray Laureen Suganob Reed Elcen Lumbay II – Objective This project aims to produce a pH indicator strip made from rose petals. The researchers want know if the rose flower is an effective acid-base indicator and if it would be precise when used to identify the pH levels of household items. III – Introduction Normally, pH indicator strips such as litmus paper are the ones used in indicating the pH level of a substance. pH is the measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. Acidic and basic are two extremes that defines chemicals. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9. ( Roses are woody perennial shrubs or vines of the genus Rosa, within the......

Ph of Household Chemicals

...| Ph of Household Chemicals | Formal Lab Report | Chemistry 1000 | | Fall 2014 | | Purpose: To determine the pH level of common household products and to determine whether they are an acid or a base using red cabbage as a pH indicator that will change colors according to the acidity levels. Hypothesis: I believe that most of the cleaning chemicals will be acidic and most of the food/edible items will be neutral. I am also predicting that personal hygiene items are also neutral due to the fact that they are put on your body. Scientific Background: “Chemists have a scaled called the pH scale that is based on hydrogen ion concentration to express the acidity or basicity of solutions. The pH scale is a logarithmic scale; a change of 1 pH unit corresponds to a tenfold change in H3O+ concentration. Each change of 1 in pH scale corresponds to a change of 10 in [H3O+].”(Tro, 2015). Acids are substances that can donate a hydrogen ion in water; bases are substances that can accept a hydrogen ion or produce hydroxide ion in water. The amount of hydrogen ion donated or accepted determines the strength of the acid or base. Variables: The independent variable would be the substances being tested. The dependent variable would be the pH of each substance. The control variables are the temperature, the volume of the pH indicator and the pH indicator itself.

Ph Buffer Using Cabbage Indicator

...Lynne Andrew NB 1110 / M 5 – 7:50 Lab 1 February 2, 2015 pH and Buffer – Using Red Cabbage Indicator to Measure pH Introduction This experiment was performed to evaluate the following hypothesis: Red cabbage indicator can be used as a measure of pH. According to Campbell, et al, in Biology: Concepts and Connections, red cabbage contains a water-soluble pigment called anthocyanin that changes color when it is mixed with an acid or a base. The pigment turns red in acidic environments with a pH less than 7 and the pigment turns bluish-green in alkaline (basic) environments with a pH greater than 7 (2012). The pH indicating property of red cabbage indicator is well accepted in the scientific community and is a useful standard for us to become familiar with. As stated in the lab text, having a known set of standards is important to gaining information about unknowns (2011). Red cabbage contains high levels of anthocyanins, which give the cabbage its deep purple hue. The pigments also change in relation to changes in pH, according to the lab text (2011). According to a University College London lab experiment titled Red Cabbage pH Indicator, with most pH indicators, the compound gains a proton at low pH (lots of H+) but loses it at higher pH. Although this may seem a slight change, it is enough to alter the wavelengths of light reflected by the compound. As a result, we see the color change with respect to pH. The lab description continues to state anthocyanins......

Ph Experiment

...Neutrals pH Scale Investigations ___ By Dominic Krusniak Our Experiment We were challenged to test the accuracy of cabbage juice as an indicator for classifying liquid solutions as an acid, base, or a neutral. We believed that red cabbage juice would be an accurate indicator for classifying liquid solutions. We came to this conclusion because we had 2 reviewed other reports testing red cabbage juice in a similar way to our method with an outcome in agreement to our hypothesis. We tested our hypothesis by gathering two tablespoons of the liquids: dish soap, ammonia, baking soda, tea, pop, lemon juice, and vinegar. We poured them into separate, clean plastic cups. We scooped two tablespoons of the cabbage juice solution into each chemical and then we observed the color changes (see the data table below). Name of Chemical Dish Soap Ammonia Baking Soda Color Changed Green Green Blue Green Tea Pop Cream of Tatar solution Grey Pink Rose Pink Pink Lemon Juice Vinegar Dark Pink Dark Pink We claim that all of the chemicals which turned a green or blue color (i.e. dish soap, ammonia, and baking soda.) were bases. Therefore, we also said that all of the chemicals that turned pink or red, where acidic. (i.e. Tea,soda,cream of tatar solution,lemon juice, and vinegar.) The above mentioned facts support our hypothesis. In an article we read to begin our lab, we learned about pH and the pH scale. We read that pH was a ranking that classified things as acidic or basic. The......

Ph on Amylase Function

...The effect of pH on salivary amylase Introduction: Saliva in the mouth contains the protein salivary amylase which acts on starches to break them down into mono- and disaccharides.(2) Saliva has been found to have an average pH level of about 6.78 +/- when tested in various locations of the mouth from multiple healthy individuals.(1) Saliva acts as a buffer against any possible changes in the pH from acids produced from bacteria, maintaining the oral cavity at an almost neutral pH level.(3) If saliva was introduced to a differing pH than its optimal pH, it would cause the amylase action to either decrease or cease functioning all together if the pH changed dramatically enough. With the given information, it could be said that salivary amylase would be at its optimal functioning level at around the average saliva pH of 6.78.(1) A change in pH would be detrimental to amylase given the protein nature of amylase and the instability of proteins in more acidic or basic pH concentrations.(3) When proteins are surrounded by an acidic pH, they become unstable due to the increase in positive charge from the disassociated hydrogen ions, the positive charge acting to pull the proteins out of their folded shape.(3) In similar opposition, when proteins are surrounded by a basic pH, they are instead pulled apart by the negative charge produced by the increased amount of hydroxide ions.(3) Methods: In this experiment, a saliva solution was procured by......

Ph Measurement and Buffer Preparation

...pH Measurement and Buffer Preparation Quilao, M.H., Regua, R., Reinoso, L.A., Rojas, K.J., Sabalberino, E.M. Abstract In this experiment, phosphate buffer solution was prepared and the pH of the buffer and samples were determined through different liquid indicators and the pH meter. Also, the buffer capacity of the prepared buffer solution was calculated. The group was tasked to prepare a 250 mL phosphate buffer solution of pH 8.0 using dihydrogen phosphate ion (H2PO4) and primary sodium phosphate monohydrate (NaH2PO4.H2O). With the aid of 6.0 M HCl and 6.0 M NaOH, the pH of the buffer was adjusted while being recorded by the pH meter until it reached the desired pH. Afterwards, the buffer solution was introduced to Colorimetric Determination which used acid-base indicators. The buffer solution changed to color yellow when Thymol and Methyl red were added, blue when Bromophenol blue and Bromocresol green were included, purple for Bromocresol purple, pink for Phenol red and Phenolphthalein, and orange for Methyl orange. Introduction The measurement of the low concentration of hydrogen ions present in any biological process is expressed as pH. pH is used to measure the acidity and alkalinity of a solution. pH involves ionic activity, making it difficult to accurately predict the pH value of a solution. The pH is also known to greatly affect our biological system and any large changes could be dangerous, which is why there is a buffer present within our......

Ph Meter

...pH meter: Vital tool for food processing A pH meter is defined as a device that measures the pH level of a liquid solution by means of knowing the voltage amount of two electrodes submerged in a solution. The use of this tool is never new to us. It is commonly utilized in science laboratory activities in school to know the acidity and basicity of household materials people see everyday. However, our perception of its application is only limited by the idea that pH meters are mere “laboratory equipment” used in school. Many overlook its importance especially in food production. People, who consume food everyday do not know that these “mere tools”, called pH meters, are vitally needed in the food processing industries. How are pH meters used in food processing? Knowing the pH level and monitoring it all throughout the process of food manufacturing is a critical step in maintaining the production of high-quality foods. Making sure that the proper pH range is achieved during the physical and chemical reactions undergone by the food in the whole duration of the process is vital. Improper interpretation of pH tests can cause a huge drawback in the production of food. Incorrect measurement of pH level in jelly production for an instance, affects the consistency of the jelly and thus the product quality as a whole. Yogurt production, as an example, is generally dependent on the pH level for if ever, the proper pH level is not reached, discoloration (Yogurt becoming yellow)......

Ph Affect on Enzymes

...pH is a way of expressing how acidic or basic a solution is. (Campbell “Biology” 8th ed. text, pp.52-53). An acid is a substance that increases the solutions concentration of hydrogen ions and a base reduces the solutions hydrogen ion concentration.(Campbell “Biology” 8th ed. text, pp.52-53). The pH scale shows us the pH values of some aqueous solutions including pure water, human blood and tears, which are the neutral solutions. (Campbell “Biology” 8th ed. text, pp.52-54). The pH of a neutral aqueous solution is seven, the midpoint of the pH scale. (Campbell “Biology” 8th ed. text, pp.52-54). The acidic solutions range from six to zero, zero being most acidic and the basic solutions range from seven to fourteen, fourteen being most basic. (Campbell “Biology” 8th ed. text, pp.52-54). However, most biological solutions range from a pH of six to eight. (Campbell “Biology” 8th ed. text, pp.52-54). However, there are exceptions, for example the acidic digestive juice of the human stomach has a pH of around two. (Campbell “Biology” 8th ed. text, pp.52-54). Therefore, like the proteins structures which are sensitive to their environment so is an enzymes which works better under certain conditions than others.(Campbell “Biology” 8th ed. text, pp.152-155). Enzymes are organic catalysts (a chemical that speeds up a reaction without changing itself) that engages in the transformation of one organic molecule to another but with a lower activation energy.(Bio 05LA Lab Manual- Lab# 5,......
