The general structure of an NH 4 OH molecule is illustrated above.. Basicity of NH 4 OH. When ammonia is dissolved in water, the water molecules donate a proton to the NH 3 molecule. This leads to the formation of an ammonium cation (whose stone formula is NH 4 +) and a hydroxide ion (OH –).This can be represented by the following equilibrium reaction.
