The standard electrode potential for the reactions, `Ag^(+)(aq)+e^(-) rarr Ag(s)` `Sn^(2+)(aq)+2e^(-) rarr Sn(s)` at `25^(@)C` are `0.80 ` volt and `-0.14 ` volt, respectively. The `emf`of the cell `Sn|Sn^(2+)(1M)||Ag^(+)(1M)Ag` is `:`A. `0.66` VB. 0.80 VC. 0.94 VD. 1.08 V |

Answer» Correct Answer - A `E_(cell)^(@) = E_(RP_(Ag))^(@) - E_(RP_(Sn))^(@)` `= 0.80 - (-0.14) = 0.94` V |
