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)

Answer»

Solution :`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`
