Statement 1 : When 0.1 m weak diprotic acid h2a dissociates with its dissociated constant ka1 = 10^3, then Ka2 = 10^8, then A^2- is almost equal to 10^3 M. Statement 2 : Since Ka2 Statement 1 : When 0.1 m weak diprotic acid h2a dissociates with its dissociated constant ka1 = 10^3 then A^2- is almost equal to 10^3 M.
