Polyprobic acids contain more than one dissociable proton. Each dissociation step has its own acid-dissociation constant. Kat. Ka elc For example, a diprotic acid H₂A reacts as follows H_A(aq) + HO(1) HO (aq) +HA (ng Kat BOHA H₂A HA (aq) + H₂O(1) H₂O (aq) + A¹ (₂) H₂O|A| Ka= (HA In general, Ka-A2 for a solution of a weak diprobic acid because H₂O HA Express your answer to two significant figures and include the appropriate units.
