Question

A diprotic acid, H2A, has acid dissociation constants of Ka1=1.01×10−4 and Ka2=4.08×10−12. Calculate the pH and molar concentrations of H2A, HA−, and A2−at equilibrium for each of the solutions.

A diprotic acid, H, A, has acid dissociation constants of Kal = 1.01 x 104 and K22 = 4.08 x 10-12. Calculate the pH and molarA 0.176 M solution of NaHA. pH= pH= ] [H,A1 = C HA) = M [AP] = A 0.176 M solution of Na,A. pH= C HA] = M [AP]-C
