The relatively close pH levels of Tap Water, Spring Water,
Flavored Water, and Seltzer Water.

Introduction
This experiment was performed to investigate the following hypothesis: The following four different types of drinking water (spring water, seltzer water, tap water, and flavored water) we test will relatively have the same pH level.
Our group decided to test different types of drinking water to see if a pH level of tap water is comparable to other types of water. Many people believe that city water has many chemicals, causing us to form the expirement to see how close the different types of drinking water’s pH levels are.
Materials and Methods
For the first part of our exiperiment we used the Red Cabbage Indicator. Red cabbage indicator is made by boiling red cabbage to extract the pigments. The red cabbage is filled with anthocyanins, therefore it can be used for an indicator. The color of the red cabbage indicator changes with different pH levels.
We needed a set of standards to compare our red cabbage and water mixtures with. We used seven different test tubes and put one type of pH level in each. The pH levels were pH 2, pH 4, pH 6, pH 7, pH 8, pH 10, and pH 12. In each tube there was ten drops of the pH level using a clean pipette. Next we added five drops of red cabbage using a clean pipette to each test tube, covered it Parafilm, and mixed the test tube. We recorded the color of each.
Next we added ten drops of the different types of drinking water using a clean pipette, one type of water in each tube. We then added five drops of the red cabbage indicator to each test tube using a clean pipette, covered it with Parafilm, and mixed the test tube. Since we had the set of standards we were able to compare the colors of the drinking water with the different pH levels, to make an educated guess on what each drinking water’s pH was.
After we had the red cabbage indicator expirement done, we tested the actual pH level of each type of drinking

    Lab on pH Levels Purpose: Throughout this experiment we are trying to learn how to take proper pH measurements using a pH meter. We also want to see the pH of different common liquids and record the change in pH when we add acids and alkaline liquids. The last reason we are conducting this experiment is to explain and show how fresh milk spoils by the change in pH. Materials: In this experiment we used graduated cylinders and glass beakers and added variety of ingredients including 50 mL of; soda…

    Distinction of pH levels of Orange Juice and Milk of Magnesia in comparison to Distilled Water Cooper, A., Do, J., Francois, F., Olaleye, O. Lab Section LA: 06/20/2012 Introduction pH is the measurement of the concentration of hydrogen ions in a certain solution. Solutions or substances that have a higher concentration of hydrogen ions are considered acidic on the pH scale. Therefore, a solution with low concentration of hydrogen ions is basic on the pH scale. The pH scale is a universal means…

    Ph Lab Report Bryon Kim 12­30­13 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic, and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap…

First the PH measurements, Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water, etc.). In regards to the absorption spectroscopy, the method by which the concentration was obtained is questionable. Was the concentration known before the experiment…
