Question

The reaction, $\frac{1}{2}{H}_2(g)+AgCl(s)\rightleftharpoons H^{+}(aq)+C{l}^{-}(aq)+Ag(s)$ occurs in the galvanic cell

• A. $Ag|AgCl(s)|KCl($ soln $)\left|AgN{O}_3\right|Ag$
• B. $Pt\left|H_2(g)\right|HCl($ soln $)\mid AgN{O}_3$ (soln) $\mid Ag$
• C. $Pt\mid H_2(g)HCl($ soln $)|AgCl(s)|Ag$
• D. $Pt\left|H_2(g)\right|KCl$ (soln) $|\mathrm{AgCl}(s)|Ag$

Answer 1

Answer: (C)

In a gaivanic cell, oxidation occur in the left hand electrode chamber and reduction in right hand electrode chamber. In the following cell.
$Pt\left|H_2(g)\right|HCl($ soln $)||AgCl(s)\mid Ag(s)$
The cell reactions are :
