The reaction
`1//2H2(g)+AgCl(s) rarr H^(o+)(aq)+Cl^(c-)(aq)+Ag(s) ` occurs in the galvanic cell.

Options

A. `Ag//AgCl(s) //KCl (solution0 AgNO_3 (sol) Ag`
B. `Pt//H_2(g) //HCl (sol)//AgNO_3 (sol)//Ag`
C. `Pt//H-2 (g) //HCl (sol)//Ag Cl(s) //Ag`
D. `PtH_(2)(g)//KCI(sol)/AgCl(s)//Ag`

Answer

C

Explanation

Anode : `1/2 H_2 (g) rarr H^(+) (aq) +e^(-)`
(Cathode : AgCl(s) +e(-)rarr Ag(s) = Cl^(-) (aq))/(1/2 H_2 (g) + AgCl(s) rarr H^= (ag) +Ag(s) +Cl^(-) (ag))`
