between eu and ce which has more oxidising capacity
Answers
Explanation:
In aqueous solution, Ce4+ converts to Ce3+ by gaining an electron so it acts as a good oxidising agent while Eu2+ in aqueous solution chenges to Eu3+ suggesting that it is agood reducing agent by donating electron.
Between eu and ce which has more oxidising capacity
Explanation:
Lanthanides and Actinides
They are called inner transition elements .
They are placed separately in periodic table.
Europium and Cerium both are f block elements .
The electronic configuration of :
Europium : [Xe]4f⁷
Cerium = [Xe]4f⁰
Mostly the oxidation states of lanthanides is +3 , but some elements with half filled and fully filled orbitals. Out of this europim and cerium is one of them as they show +4 and +2.
Europium shows oxidation state : +2
Cerium shows oxidation state : +4
If we compare their oxidation capacity : Ce in its +4 , in aqueous solution is good oxidising agent as the most stable state of cerium is +3. Thus, Ce4+ is good oxidising agent because and transforms to the most stable +3 oxidation state by gaining one electron.
