The e.m.f. of the cell obtained by combining `Zn` and `Cu` electrode of a Daniel cell with N calomel electrode in two different arrangements are `1.083V` and `0.018V` respectively at `25^(@)C`. If the standard reduction potential of N calomel electrode is `0.28V` find the emf og Daniel cell. |

Answer» Correct Answer - `E = 1.1V` `E_(cell) = E_(ZN//Zn^(2+)) +E_(calomel(Red))` `E_(ZN//Zn^(2+)) = 0.803` `E_(cell) = E_(Cu^(2+)//Cu)` `E_(cell) = 1.1V` |
