A student was given a 0.15 M solution of an unknown diprotic acid H2A and asked to determine the Ka1 and Ka2 values for the diprotic acid. The student titrated 59.6 mL of the 0.15 M H2A with 0.15 M NaOH. After 29.8 mL of NaOH was added, the pH of the resulting solution was 6.37. After 59.6 mL of NaOH was added, the pH of the resulting solution was 8.34. What are the values of Ka1and Ka2 for the diprotic acid?

Question

A student was given a 0.15 M solution of an unknown diprotic acid H₂A and asked to determine the K_a1 and K_a2 values for the diprotic acid. The student titrated 59.6 mL of the 0.15 M H₂A with 0.15 M NaOH. After 29.8 mL of NaOH was added, the pH of the resulting solution was 6.37. After 59.6 mL of NaOH was added, the pH of the resulting solution was 8.34. What are the values of K_a1and K_a2 for the diprotic acid?
