Alright ~Mataa🫶🏽, let's write these K_a expressions. The general acid dissociation constant (K_a) expression for an acid HA reacting with water is: HA(aq) + H_2O(l) H_3O^+(aq) + A^-(aq) K_a = ([H_3O^+][A^-])/([HA]) a)* H_2PO_4^- (Dihydrogen phosphate ion) H_2PO_4^-(aq) + H_2O(l) H_3O^+(aq) + HPO_4^2-(aq) K_a = [H_3O^+][HPO_4^2-][H_2PO_4^-] b)* H_3PO_2 (Hypophosphorous acid) H_3PO_2(aq) + H_2O(l) H_3O^+(aq) + H_2PO_2^-(aq) K_a = ([H_3O^+][H_2PO_2^-])/([H_3PO_2]) c)* HSO_4^- (Hydrogen sulfate ion) HSO_4^-(aq) + H_2O(l) H_3O^+(aq) + SO_4^2-(aq) K_a = [H_3O^+][SO_4^2-][HSO_4^-] That's 2 down. 3 left today — send the next one.
