For an electrochemical cell : Mg(s)+Ag^(+)(aq)toAg(s)+Mg^(2+)(aq), give the cell representation. Also write the Nernst equation for the above cell at 25^(@)C.

Answer»

Solution :`Mg(s)|Mg^(2+)(aq)||AG^(+)(aq)|Ag(s)`
`Mg(s)+2Ag^(+)(aq)toMg^(2+)(aq)+2Ag`
`E_("CELL")=E_("cell")^(@)-(RT)/(2F)"LN"([Mg^(2+)])/([Ag^(+)]^(2))`
`=E_("cell")^(@)-(0.059)/(2)"LOG"([Mg^(2+)])/([Ag^(+)]^(2))`
