Why ` Ce(OH)_(3)` is more basic than `Lu(OH)_(3)` ?

Text Solution

AI Generated Solution

To determine why \( \text{Ce(OH)}_3 \) is more basic than \( \text{Lu(OH)}_3 \), we need to analyze the properties of the lanthanide hydroxides and the factors affecting their basicity. ### Step-by-Step Solution: 1. **Understanding Basicity**: Basicity refers to the ability of a compound to donate hydroxide ions (\( \text{OH}^- \)) in solution. The more readily a compound can release hydroxide ions, the more basic it is. 2. **Lanthanide Series**: The lanthanide series consists of elements from lanthanum (La) to lutetium (Lu). Cerium (Ce) is located towards the beginning of this series, while lutetium (Lu) is at the end. ...
