Solutions

Expert Solution

AgCl(s) + e⁻

⇌

Ag(s) + Cl⁻

E^o(V) = +0.22233

2 H⁺ + 2 e⁻

⇌

H₂(g)

E^o(V) = 0.0000

here the one which is having higher reduction potential will get reduced first.We have Ag having higher reduction potential so it will get reduced from Ag+ to Ag,whereas H₂ will get oxidized

The oxidation reaction which occurs at the anode would be

H₂ 2H⁺(aq) + 2e^–

the reduction which occurs at the cathode would be

AgCl(s) + e^– Ag(s) + Cl^–

Overall Cell reaction will be

2AgCl(s) + H2(g) 2Ag(s) + 2H+ (aq) + 2Cl– (aq)
