Among the following, identify the correct statement
Answer» Chloride ion oxidised `O_(2)` `FE^(2+)` is oxidised by iodine IODIDE ion is oxidised by chlorine `Mn^(2+)` is oxidised by chlorine Solution :`2I^(-)+Cl_(2)toI_(2)+2Cl^(-)` `E^(o)=E_(I^(-)//I_(2))^(o)+E_(Cl_(2)//CL^(-))^(o)` `=-0.54+1.36` `E^(o)=0.82V` `E^o` is positive HENCE iodide ion is oxidized by chlorine.
