Why Eu^(2+) and Yb^(2+) ions in solution...

Why `Eu^(2+)` and `Yb^(2+)` ions in solutions are good reducing agents but an aqueous solution of `Ce^(4+)` is a good oxidising agent?

Text Solution

Verified by Experts

The most stable oxidation state of lanthanides is +3, hence ions in +2 state tend to change to +3 state by loss of electron and those in +4 state tend to change to +3 state by gain of electron
