Which one of the following statements related to lanthanons is incorrect ?
- A Europium shows \(+2\) oxidation state.
- B The basicity decreases as the ionic radius decreases from \(Pr\) to \(Lu.\)
- C All the lanthanons are much more reactive than aluminium.
- D \(Ce(+4)\) solutions are widely used as oxidizing agent in volumetric analysis.
Answer & Solution
Correct Answer
(C) All the lanthanons are much more reactive than aluminium.
Step-by-step Solution
