None DOxalic acid (H2C2O4) is a weak diprotic acid. Although this acid is weak, the ionization constant for the dissociation of its first proton,Ka1, is sufficiently large to not allow us to ignore the change in its initial concentration. Consider a solution of oxalic acid prepared bydissolving 5.82 g of oxalic acid dihydrate (H2C2O4 2H2O) in 57 ml of water.
