I. Strong Acids and Bases Exp. 6 Date Performed: 2/24/11 Name: Breanna Jameson Date Submitted: 3/3/11 Partner: Megan Dees Chemistry 1045L-35 Tong Chen II. Purpose The combining of a strong acid (HCl) and a strong base (NaOH) combine to make serial dilutions, which combine to form a salt solution. The experiment also included making dilutions of either the strong acid or the strong base. Then measuring the pH and seeing how the dilutions affected that. The experiment deals with methods in how to compute the pH of a solution as well as the concentration using specific formulas. Also, the experiment allowed the students to learn how to use a pH meter.
