Out of LU(OH)3 and La(OH)3 which is more basic and why?

1.	Out of LU(OH)3 and La(OH)3 which is more basic and why?
Answer» 1. As we move from Ce³⁺ to Lu³⁺ , the basic character of Lu³⁺ ions decreases. 2. Due to the decrease in the size of Lu³⁺ ions, the ionic character of Lu – OH bond decreases, covalent character increases which results in the decrease in the basicity. 3. Hence, La(OH)₃ is more basic than Lu(OH)₃.
