Please Help a) Calculate the pH of a solution initially 0.1 M in acetic acid and 0.02 M in sodium acetate. The pKa for acetic acid is 4.76. B) calculate the pH of the buffer if you add 10 ml of 0.1 M HCL to 100ml of the buffer in part a.
In this experiment you will be measuring pH for several different solutions. A pH probe will be used rather than pH paper as it will be more accurate. You will be testing the pH of six solutions: deionized water, 0.1 M HCl, 0.1 M HCH3COO, 0.1 M NaCH3COO, 0.1 M NaOH, and a buffer made by mixing equal parts of HCH3COO and NaCH3COO. You will measure the pH of each solution three times: Neat - just the solution After the...
