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
