  Identify the correct statement(s) in relation to the following reaction : \[Zn+2HCl\to ZnC{{l}_{2}}+{{H}_{2}}\] (a) Zinc is acting as an oxidant.                                   (b) Chlorine is acting as a reductant. (c) Hydrogen ion is acting as an oxidant.                (d) Zinc is acting as a reductant.

Answer:

  (c, d)\[\overset{0}{\mathop{Zn}}\,+2\overset{+1-1}{\mathop{HCl}}\,\to \overset{+2-2}{\mathop{ZnC{{l}_{2}}}}\,+\overset{0}{\mathop{{{H}_{2}}}}\,\] Zn (oxidised) ® Act as reductant Hydrogen (reduced) ® Act as oxidant
