1.	For some reactions the standard reduction potentials are given below : `Zn^(2+) + 2 e to Zn , " " E^(@) = -0.762 V` `Fe^(2+) + 2e to Fe , " " E^(@) = -0.440 V` `Cu^(2+) + 2e to Cu , " " E^(@) = + 0.345 V` `Ag^(+) + e to Ag " " E^(@) = + 0.800V` Which one of the following is most easily oxidised ?A. ZnB. CuC. FeD. Ag
Answer» Correct Answer - A Less the reduction potential or greater the oxidation potential , more easily the substance is reduced `E_(Zn)^(@) lt E_(Fe)^(@) lt E_(Cu)^(@) lt E_(Ag)^(@)` .
