Question

whyCe3+is more basic thanCe4+?​

Answer 1

Answer:

This is because extracting 4 electrons from an atom requires huge amount of energy. It requires a really strong oxidising agent to oxidise state 3 to state 4 which must have the electron gain enthalpy greater than the ionisation energy of the Ce(III) which can provide enough energy to knock out electron from Ce(III).
