Write the Nernst equation for the cell reaction in the Daniel cell. How will the E_("cell")be affected when concentration Zn^(2+) ions is increased ?

Answer»

Solution :The following reaction takes PLACE
`Zn + Cu^(2+) to Zn^(2+) + Cu`
The Nernst EQUATION MAY be written as
`E_("cell") = E_("cell")^(@) - 0.059/2 log ([Zn^(2+)])/([Cu^(2+)])`
`E_("cell")` decreases when CONCENTRATION of `Zn^(2+)` ions increases.
