Calculate the `EMF` of a Daniel cell when the concentartion of `ZnSO_(4)` and `CuSO_(4)` are `0.001M` and `0.1M` respectively. The standard potential of the cell is `1.1V`. |

Answer» Correct Answer - `E = 1.158V` `E_(cell) = (E_(cell)^(@) - (0.0591)/(2) log .([Zn^(2+)])/([Cu^(2+)]))` `= 1.1 -(0.0591)/(2)log.([10^(-3)])/([10^(-1)])` `= 1.1 +0.0591` ltbr. `=1.1591V` |
