 * TESTING THE SOLUBILITY OF ANTIPERSPIRANTS AT VARYING pH LEVELS** . **Annie and Claire.** Antiperspirant contains aluminum, an element that has been previously proven to potentially cause breast cancer and Alzheimer’s disease. One way to reduce the risk of getting these life threatening illnesses, research shows, is to thoroughly wash the antiperspirant from the underarm. In this lab, the solubility of an antiperspirant in pH solutions, which were created by diluting hydrochloric acid (to make acids) and sodium hydroxide (to make bases), ranging from a pH of 1.48-pH 13.27 was tested. From the results, pH 3.20 and pH 9.22 have the highest solubility rates, while pH 12.45, 13.15, and 13.27 have the lowest solubility rates. In addition, the solubility of antiperspirant in a soap with a pH of 6.25 was tested, but the results appeared more like that of a more basic solution.
