Given : `E^(@) (Cu^(2+//Cu)` = 0.337V` and `E^(@) (Sn^(2+//Sn) = -0.136V`. Which of the following statements is correct?A. `Cu^(2+)` ions can be reduced by `H_(2)(g)`B. `Cu` can be oxidized by `H^(+)`C. `Sn^(2+)` ions can be reduced by `H_(2)(g)`D. `Cu` can reduce `Sn^(2+)` |

Answer» Correct Answer - A As `E_(Ce^(+))^(@)toCu=0.337VgtE_(H^(+)//H_(2))^(0)` `therefore` `Cu^(2+)` can be reduced by `H_(2)` |
