उत्तर
On reaction with metals, hydrochloric acid forms respective chlorides and liberates hydrogen.
\[\ce{Zn + 2HCl -> ZnCl2 + H2 ^}\]
On reaction with oxidizing agents, hydrochloric acid forms respective salts water and pungent smelling, greenish yellow chlorine gas.
\[\ce{\underset{\text{Manganese
dioxide}}{MnO2} + 4HCI -> \underset{\text{Manganese chloride}}{MnCl2(aq)} +2H2O +C12 ^}\]
