The reaction
`(1)/(2)H_(2)(g)+AgCl(s)hArrH^(+)(aq)+Cl^(-)(aq)+Ag(s)`
occurs in the galvanic cell

Options

A. `Pt|H_(2)(g)|KCl_((" soln".))||AgCl(s)|Ag`
B. `Pt|H_(2)(g)|HCl_(("soln".))||AgCl(s)|Ag`
C. `Pt|H_(2)(g)|HCl_(("soln"))||AgNO_(3)|Ag`
D. `Ag|AgCl(s)|KCl_(("soln"))|H_(2)(g)|Pt`.

Answer

B

Explanation

Here half cell reaction are
`(1)/(2)H_(2)rarrH^(+)+e^(-)` (At anode )
`Ag^(+)+e^(-)rarrAg` (At cathode)
`therefore` Cell representations is
`Pt|H_(2)(g)|HCl("soln")||AgC l(s)|Ag`
