Question

What is the reduction half-reaction for the reaction of zinc with hydrochloric acid?

Answer 1

2HCl (aq) + Zn²⁺   ⇒  ZnCl₂  + 2H⁺         Total Reaction 
    
Leo goes Ger (Lose electron oxidize, Gain electron reduction)

Zn²⁺ + 2e⁻  ⇒ Zn     Oxidation half-reaction 

2H ⇒ 2H⁺ + 2e⁻       Reduction half-reaction
