For an electrochemical cell : Mg(s)+Ag^(...

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`.

Text Solution

Verified by Experts

`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))`
