WebH 3 O + is given by water is neglected because dissociation of water is very low compared to the acetic acid dissociation. Because H 3 O + concentration is known now, pH value … WebThe ammonium ion is the conjugate acid of the base ammonia, NH 3; its acid ionization (or acid hydrolysis) reaction is represented by. NH 4 + ( a q) + H 2 O ( l) ⇌ H 3 O + ( a q) + NH 3 ( a q) K a = K w / K b. Since ammonia is a weak base, Kb is measurable and Ka > 0 (ammonium ion is a weak acid). The chloride ion is the conjugate base of ...
