c) Write Nernst equation for the cell represented as: `Mg(s)|Mg_((aq))^(+2)||Al_((aq))^(3+)|Al_((S))`. 

Text Solution

Verified by Experts

The cell reaction according to the cell representation is `[Mg|Mg^(+2)||Al^(3+)|Al]`
`3Mg+2Al^(3+)rarr 3Mg^(2+)+2Al`
Nernst equation for the given cell is
`E_("cell")=E_("cell")^(Theta)-(0.059)/(6)log""([Mg^(2+)]^(3))/([Al^(3+)]^(2))`
