State the factors which influence the value of cell potential in the following cell.
`Mg | Mg^(2+)(aq) || Ag^(+)(aq) | Ag(s)`

Text Solution

Verified by Experts

The cell reaction is `Mg(s)+2Ag^(2+)(aq)toMg^(2+)(aq)+2Ag(s),n=2`
`therefore` Nernst equation is `E_(cell)=E_(cell)^(@)-2.303(RT)/(2F)"log"([Mg^(2+)])/([Ag^(+)]^(2))`
