Question

A student is titrating a 30mL solution of a 0.75M diprotic acid with 0.25M NaOH in a laboratory experiment. Given that Ka1 = 5.5 x10^(-5) and Ka2 = 2.8 x10^(-10), answer the questions that follow.

(A) Calculate the pH of the resulting solution after 60 mL of the strong base titrant has been added. Write answer in THREE SIGNIFICANT FIGURES. 

Answer 1

pH of the resulting solution=4.77
