1.	An iron rod is immersed in a solution containg 1.0 M NiSO_(4) and 1.0 M ZnSO_(4) predict giving reasons which of the following reaction is likely to proceed ? (i) Fe reduces Zn^(2+)ions (ii) Iron reduces Ni^(2+)ions given E_(Zn^(2+)//Zn)^(@)=-0.76V,E_(Fe^(2+)//Fe)^(@)=-0.44V "and" E_(Ni^(2+)//Ni)^(@)=-0.25V
Answer» Solution :(i) since `E^(@)` of ZN is more negative than that of fe therefore zn will be oxidised to `Zn^(+)` IONS while `Fe^(2+)` ions will be reduced to fe in other words fe wil not reduce `Zn^(2+)` ions (ii) since `E^(@)` of Fe is more negative than that of ni therefore fe will be oxidized to `Fe^(2+)` ions while `Ni^(2+)` ions will be reduced to Ni thus fe reduces `Ni^(2+)` ions
