Step-by-Step Solution
Diazotization is the chemical process of converting an aromatic primary amine into a diazonium salt by treating it with nitrous acid at low temperatures ranging from 273 to 278 Kelvin. Nitrous acid is generated in situ by the reaction of sodium nitrite with hydrochloric acid. The chemical equation for diazotization of aniline is $C_6H_5NH_2 + NaNO_2 + 2HCl \rightarrow C_6H_5N_2^+Cl^- + NaCl + 2H_2O$. These diazonium salts are highly reactive intermediates used in the synthesis of various azo dyes.
