Calculate the ph of the following solutions of acetic acid, K. 1.8x 10* For clarity, show or explain any approximations you make (in other words, when appropriate, say why you made the approximation). a. What is the initial pH and percent ionization of a 0.125 M solution of acetic acid? b. What is the pH of a buffer solution made by mixing 40.0 ml of O.125 M acetic acid with 50.0 ml of 0.100 M sodium acetate? c. What is the pH of the buffer made in part b if 5.0 ml of 0.100 M NaOH are added to the buffer?
