Professor PC Thomas Classes · Answer

In acid medium the oxygen atoms gets protonated to form oxonium ion which enhances the nucleophilic attack of $\mathrm{H}_{2} \mathrm{~N}-\mathrm{OH}$\ When pH is too low ie in strong acid medium, $\mathrm{H}_{2} \mathrm{~N}-\mathrm{OH}$ forms its salt with acid.\
