A 10.0 mL sample of 0.25 M NaOH(aq) is titrated with 0.10 M HCl(aq) (adding HCl to NaOH). Determine which region on the titration curve the mixture produced is in, and the pH of the mixture at each volume of added acid. Assume that the volumes of the solutions are additive.
Part a):
1) After adding 15.0 mL of the HCl solution, the mixture is [ Select ] ["at", "before", "after"] the equivalence point on the titration curve.
2) The pH of the solution after adding HCl is [ Select ] ["7.00", "12.60", "1.40", "11.00"] .
