Q.
The reaction,

$\frac{1}{2} H_{2 (g)} + {AgCl}_{(s)} \to H_{(a q)}^{+} + {Cl}_{(a q)}^{-} + {Ag}_{(s)}$

occurs in which of the following galvanic cell: [2024]

1 ${Pt|H}_{2 (g)} | {HCl}_{(soln .)} {|AgCl}_{(s)} | Ag$

2 ${Pt|H}_{2 (g)} | {KCl}_{(soln .)} {|AgCl}_{(s)} | Ag$

3 ${Ag|AgCl}_{(s)} | {KCl}_{(soln .)} {|AgNO}_{3 (aq)} |Ag$

4 ${Pt|H}_{2 (g)} | {HCl}_{(soln .)} {|AgNO}_{3 (aq)} |Ag$

Ans.
(2)

Anode half cell reaction (Gas-ion electrode):

$\frac{1}{2} H_{2} (g) \to H^{+} (a q) + e^{-}$

Cathode half cell reaction (metal-metal insoluble salt-anion electrode):

$AgCl (s) + e^{-} + K^{+} (a q) ⇌ Ag (s) + KCl (a q)$

Net cell reaction:

$\frac{1}{2} H_{2} (g) + AgCl (s) + K^{+} (a q) ⇌ H^{+} (a q) + Ag (s) + KCl (a q)$

Cell representation:

${Pt|H}_{2} (g) | KCl (aq) | AgCl (s) | Ag (s)$
