Expert Answer
Ammonia and ammonium salts or compounds being highly soluble in water, do not occure as minerals.
As we know salts are ionic compounds and water is a polar covalent compounds so the water molecule pull apart the ammonium chloride lattice as a result of dipole dipole interactions of the charged ions in the lattice in the reaction called hydration NH4Cl dissolves to yield [NH4]+ and [Cl]- ions.
The dissociation of NH4Cl in water is as follows:
NH4Cl(s) → NH4+ (aq) + Cl-(aq)
