WebSo, hydrochloric acid (HCl) is a stronger acid than hydrobromic acid (HBr). Based only on its polarity, one might expect HF to be stronger than HCl. How is a strong acid classified? Strong acids are defined by their pKa. The acid must be stronger in aqueous solution than a hydronium ion, so its pKa must be lower than that of a hydronium ion. WebThe ammonium ion is the conjugate acid of the base ammonia, NH3; its acid ionization (or acid hydrolysis) reaction is represented by NH4+(aq)+H2O(l) ⇌ H3O+(aq)+NH3(aq) NH 4 + ( a q) + H 2 O ( l) ⇌ H 3 O + ( a q) + NH 3 ( a q) Ka = Kw/Kb K a = K w / K b Since ammonia is a weak base, K b is measurable and K a > 0 (ammonium ion is a weak acid).
