Select the incorrect statement among following: Ce4+ can act

Last updated: 7/10/2022

Select the incorrect statement among following: Ce4+ can act as good oxidizing agent Fe3+ / Fe2+ redox couple has more positive electrode potential than Mn3+/Mn2+ couple. Of the d4 species Cr2+ is strongly reducing while manganese(III) is strongly oxidising. Cobalt(II) is stable in aqueous solution but in the presence of strong field i.e. CN and NO2- complexing reagents it is easily oxidised.
