HCN + H20 -> H30+ + CN-
Term
H2S
Definition
Weak Acid Hydrogen sulfide
H2S + H2O --> H3O+ + HS-
Term
H2O
Definition
Weak Acid/Base Water
H2O -> H+ + OH-.
Term
NH4+
Definition
Weak Acid: Conjugate acids
of weak bases
Term
NH3
Definition
Weak Base Ammonia

NH3 + HOH <==> NH4+ + OH-
A few interactions between ammonia and water will result in this case, were ammonia acts as a Bronsted-Lowry base and water acts as an acid.

NH3 + H2O <==> NH2- + H3O+
But a fraction of the interactions between ammonia and water will produce this reaction since both ammonia and water are amphoteric.

But in fact, the majority of NH3 molecules in aqueous solution stay NH3 molecules and don't react at all.
