9/18/2017 · Use the litmus paper to determine which are acids and which are bases. Here are the pH levels of some other substances that you might test: Lemon juice (2) Vinegar (3) Milk (6) Egg whites (8) Baking soda (9) Ammonia (10) Human blood has an ideal pH of 7.4; even slight fluctuations can seriously affect our bodies.
A Simple pH Experiment to Do in a Class. Most liquids, such as vinegar, fruit juice and ammonia, have either acidic or basic properties. Substances that release hydroxide ions are basic, and those that let go of hydrogen ions are acidic. The pH scale, which ranges from 0 to 14, measures the acidity of a substance. You …
For an experiment, a student reviews the major ingredients in brand-name antacids, tests their pH and hypothesizes which is the most effective. To test the pH of the medicine, the student crushes…
The general results obtained in the experiment were that the best buffer capacity using hydrochloric acid were in the next order: 4.27 with a 0.39 ml/ pH unit, 4.03 with a 0.15 ml/ pH unit and 3.74 with a 0.08 ml/ pH .

Acid Base Reactions & pH Experiments – Home Science Tools, This pH is the “initial point” in your titration. Dispense approximately 0.5-mL of the 0.2 M (ce{NaOH}) solution from your buret into your beaker. Reading the buret carefully, record the exact volume added on your data sheet. Use the pH meter to measure the pH of the solution following this addition.
9/22/2019 · Measure the amount of vitamin C ( ascorbic acid) in orange juice (or another juice). Test to see how the amount of vitamin C changes after the juice is exposed to air (or light or heat). Simulate acid rain by adding an acid to water. You can use pH paper to test whether the acidity is changed after water is run through different types of soil or …
