Calculate EMF of the cell in which the given reaction occurs :
`Ni(s)+2Ag^(+)(0.002M)rarr Ni^(2+)(0.160M)+2Ag(s)`
Given, `E_("cell")^(@)=1.05V`.

Text Solution

Verified by Experts

The given cell is represented as :
`Ni(s)|Ni^(2+)(0.160M)||Ag^(+)(0.002M)|Ag(s)`
Applying Nernst equation to the given cell, we get
`E_("cell")=E_("cell")^(@)-(0.059)/(2)log.([Ni^(2+)])/([Ag^(+)]^(2))`
`=1.05-(0.059)/(2)log.(0.160)/((0.002)^(2))=0.914V`
