उत्तर
Common salt solution is added to silver nitrate solution.
AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
Common salt is NaCl, in aqueous medium it ionizes to form Na+ and Cl- ions.
NaCl(aq) → Na+(aq) + Cl-(aq)
Cl-(aq) + Ag+(aq) → AgCl(s)
On adding ammonia solution to it, the silver chloride gets dissolved and the following reaction occurs:
AgCl(s) + 2NH3(aq) → [Ag(NH3)2]+(aq) + Cl-(aq)
