Across the lanthanide series,the basicity of the lanthanoide hydroxides:

A

Increases

B

First increases than decreases

C

Decreases

D

Remain same

Text Solution

Verified by Experts

The correct Answer is:
C
`M(OH)_(3)` is a lanthanoid hydroxide. In lanthanoid series, ionic radii decreases and increasing covalent character. Thus, basicity decreases.
