Acetic acid, HC2H3O2, is a weak acid (Ka= 1.8 * 10^-5). solution A is 100.0mL of 0.10 M acetic acid, and Solution B is prepare by adding 0.0050 mol solid NaOH to solution A. One more 0.0050 mol of solid NaOH is added to solution Solution B to make Solution C. the solution D is adding 0.0050 mol more solid NaOH into solution C. Compute the pH for each of the solution A, B, C and D. Presume the volume of the solutions keeps unchanged.
