Zn added to HCl yields the spontaneous reaction

Oxidation-Reduction Reactions. Zn added to HCl yields the spontaneous reaction Zn( s ) + 2H + ( aq ) ? Zn 2+ ( aq ) + H 2 ( g ). The oxidation number of Zn has increased from 0 to 2+. The oxidation number of H has reduced from 1+ to 0. Zn is oxidized to Zn 2+ while H + is reduced to H 2 .
