An unknown metal M displaces nickel from (II) sulphate solution but do – InterviewSolution

1.	An unknown metal M displaces nickel from (II) sulphate solution but does not displace manganese from manganese sulphate solution . Which order represents the correct order of reducing power ?
Answer» `Mn gt Ni gt M` `Ni gt Mn gt M` `Mn gt M gt Ni` `M gt Ni gt Mn`. Solution :M has higher OXIDATION potential than Ni but LOWER oxidation potential than Mn , i.e., Oxidation potential are `Mn gt M gt ` Ni . GREATER the oxidation potential , greater is the reducing power.
