In aqueous solutions `Eu^(2+)` acts as

Options

A. An oxidising agent
B. Areducing agent
C. Can act either of these
D. Disproportionates in solution

Answer

B

Explanation

For all lanthanides the `+3` oxidation state is the most stable. Hence the `+2` oxidation state has a tendency to convert to `+3` making `Eu^(2+)` a good reducing agent.
