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

Text Solution

Verified by Experts

`E_("cell")^(@) = E_R^@ - E_L^@`
`E_(Zn//Zn^(2+)) = 0.76 V`
`E_(Cu^(2+)//Cu) = -0.34V`
`E_("cell")^(@) = 0.76 - (-034)`
`E_("cell")^(@) = +1.1V`.
