Question

The reaction
`1//2Hg(g)+AgCl(s) rarr H^(o+)(aq)+Cl^(c-)(aq)+Ag(s) ` occurs in the galvanic cell.
A. `Ag|AgCl(s)|KCl(sol)|AgNO_(3)|Ag`
B. `Pt|H_(2)(g)|HCl(sol)|AgNO_(3)(SOL)|Ag`
C. `Pt|H_(2)(g)|HCl(sol)|AgCl(s)|Ag`
D. `Pt|H_(2)(g)|KCl(sol)|AgCl(s)|Ag`

Answer 1

Correct Answer - c
`(1)/(2)Hg_(2)(g)+AgCl(s)rarr H^(o+)(aq)+Cl^(c-)(aq)+Ag(s)`
There is oxidation of hydrogen and reduction of silver, therefore, it occurs in the following cell `:`
`Pt|H_(2)(g)|HCl(sol)|AgCl(s)|Ag`
