For some reactionsthe 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 ?

Answer»

Zn
Cu
Fe
Ag

SOLUTION :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)^(@)` .
