In this experiment the students will be determining the pH of household products along with other solutions using several different indicators as well as a pH meter. The experiment also has the student determining what the buffer solution is in an aqueous solution. The student will also be testing the pH of milk of magnesia and will see how it affects the stomach acid. Lastly the student will be using the carbon dioxide found in their breath to neutralize a base.…
