The metal-insoluble salt electrode consists of a metal M coated with a porous insoluble salt MX In a solution of `X^(-),` A good example is Ihe silver, silver-chloride electrode for which the half-cell reaction is `AgCI(s)+e Leftrightarrow Ag(s) + CI (aq),` where, the reduction of sold silver chloride produces solid silver and releases chloride ion into solute for the cell
`M(s)|M^(2+) (aq)||Ag^(+) (aq)|Ag(s)" "E_(M//M^(2+))^(@)=+2.37V and E_(Ag//Ag)^(@)=+0.80V`
The reaction: `1/2H_(2) (g) +AgCl(s) to H^(+) (aq)+Cl^(-) (aq)+Ag(s)` occurs in the galvanic cell

A

`Ag|AgCl(s)|KCl(aq)|AgNO_(3)(aq)|Ag`

B

`Pt|H_(2)(g)|HCl(aq)|AgNO_(3)(aq)|Ag`
