Represent the cell in which the following reaction takes place
`Mg(s)+2Ag^(+)(0.0001M) to Mg^(2+) (0.130M)+2Ag(s)`
Calculates its `E_(cell)` if `E_("cell")^(Θ)=3.17V`

Text Solution

Verified by Experts

The cell can be written as `Mg|Mg^(2+) (0.130 M) ||Ag^(+)(0.0001M)|Ag`
`E_("(Cell)") = E_("(Cell)")^(ө) - (RT)/(2F) ` In `([Mg^(2+)])/([Ag^(+)]^(2))`
` = 3.17 V - (0.059V)/(2) log (0.130)/((0.0001)^(2)) = 3.17 V - 0.21V = 2.96 V`
