Which one of the following statements related to lanthanoids is incorrect?
- AEuropium shows + 2 oxidation state.
- BThe basicity decreases as the ionic radius decreases from Pr to Lu.
- CAll the lanthanons are much more reactive than aluminium.
- DCe(+4) solutions are widely used as oxidizing agent in volumetric analysis.
