Represent the cell in which following reaction takes place `:`
`Mg(s)+2Ag^(o+)(0.0001M)rarr Mg^(2+)(0.130M)+2Ag(s)` calculate its `E_(cell)` if `E^(c-)._(cell)=3.17V. `

Text Solution

Verified by Experts

`n=2`
The Nernst equation for the cell is :
`E=E^(theta)-(0.059)/(2)log.([Mg^(2+)])/([Ag^(+)]^(2))`
`=3.17-(0.059)/(2)log.(.130)/((.0001)^(2))`
`=3.17-0.21=2.96V`
