Question

The reaction, $\frac{1}{2} H _{2}(g)+ AgCl (s) \rightleftharpoons H ^{+}(a q)+ Cl ^{-}(a q)+ Ag (s)$ occurs in the galvanic cell

• A. $Ag | AgCl (s)| KCl ($ soln $)\left| AgNO _{3}\right| Ag$
• B. $Pt \left| H _{2}(g)\right| HCl ($ soln $) \mid AgNO _{3}$ (soln) $\mid Ag$
• C. $Pt \mid H _{2}(g) HCl ($ soln $)| AgCl (s)| Ag$
• D. $Pt \left| H _{2}(g)\right| KCl$ (soln) $|\operatorname{AgCl}(s)| Ag$

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 :
