1.	For a polyprotic acid, H_(3)PO_(4) its three dissociation constanst K_(1),K_(2) and K_(3) are in the order
Answer» `K_(1) = K_(2) gt K_(3)` `K_(1) = K_(2) = K_(3)` `K_(1) gt K_(2) gt K_(3)` `K_(1) lt K_(2) lt K_(3)` SOLUTION :For any polyprotic acid `H_(3)A`, the successive dissociation constants reduces as `K_(1) gt gt K_(2) gt gt K_(3)`.
