Preparation of Carboxylic Acids

WHY Eu2+ ,Yb2...

Question

WHY Eu2+ ,Yb2+, are strong reducing agent whereas Tb4+ is an oxidising agent?

Open in App

Solution

Most stable oxidation state of lanthanides is +3 . But some of the lanthanides such as Eu ,Yb and Tb exist in +2 and +4 oxidation state.
Thus to revert to thye stable +3 oxidation state.Thus Eu²⁺ gets oxidised to Eu⁺³ oxidation state and Yb²⁺ gets oxidised to Yb⁺³ oxidation state and thus act as reducing agent.
Similarly Tb⁺⁴ gets reduced to Tb⁺³ in aqueous solution and thus acts as a good oxidising agent.
