Formula. The dissociation of ammonia in water is as follows: NH 3 (aq) + H 2 O(l) ⇔ NH 4 + (aq) + OH-(aq) The reaction of acetic acid with ammonia produces ammonium acetate, which is a strong electrolyte because it dissociates more readily in water increasing the ion concentration: CH 3 CO 2 H(aq) + NH 3 (aq) → NH 4 CH 3 CO 2 (aq) Safety: Carbonic acid. Suppose sodium hydrogen phosphate (Na 2 HPO 4) was added to ammonia. phosphate and acetate can cover the entire pH range of 2
