Using the calculated emf value of zinc and copper electrode, calculate the emf of the following cell at `25^(@)C`.
`Zn(s)abs(Zn^(2+)(aq, 1M))abs(Cu^(2+)(aq, 1M))Cu(s)`

Text Solution

Verified by Experts

`Zn_((s))abs(Zn_(aq, 1M)^(2+))abs(Cu_(aq, 1M)^(2+))Cu_((s))`
`E_(Zn//Zn^(2+))^(@)=0.76 V`
`E_(Cu^(2+)|Cu)^(@)=0.34V`
`E_("Cell")^(@)=E_("ox")^(@)+E_("red")^(@)`
`" "=0.76+0.34`
`E_("Cell")^(@)=1.10V`
