OCN- + H+ <=> HOCN

This statement is NOT true. Recall that indicator values are ONLY valid at certain pH ranges. Ammonia DOES NOT qualify an Arrenhius base because arrenhius bases dissociate to give hydroxide ions in aqueous solution. Ammonia is correctly classified as Bronsted Lowry base. Recall the strength of acid or base is determined how well it dissociates or ionizes in solution , while the concentration tells you HOW MUCH of an acid or base is present. They are entirely two unrelated terms. When small amounts of acid is added, the salt is the best source to "Mop up" excess protons.
