Consider barium hydroxide, Ba(OH)2, a white powdery substance. Student A prepares a solution of Ba(OH)2 by dissolving 4.23 g of Ba(OH)2 in enough water to make 455 ml of solution.

(a) What is the pH of student A's solution?

(b) Student B was asked to prepare the same solution as student A. Student B's solution had a pH of 13.51. Did student B add more or less Ba(OH)2 to his solution? How much more or less Ba(OH)2 was added?

(c) Student C was asked to add 0.60 g of NaOH to student A's solution. What is the pH of student C's solution? (Assume no volume change.)
