Calculate standard potential of cell E(c...

Calculate standard potential of cell `E_(cell)^(0)` by using `E^(0)_(Al^(3+) | Al)` and `E_(Cu^(2+)| Cu )^(0)` as –1.66V and + 0.34V respectively

Text Solution

Verified by Experts

`E_(cell)^(0) = E_((Cu^(2+))^(0)|Cu) - E_((Al^(3+))^(0)|Al) ` = 0.34 –( -1.66) = 2.0 V
