AI Generated Solution

To determine which hydroxide is more basic between La(OH)₃ (lanthanum hydroxide) and Lu(OH)₃ (lutetium hydroxide), we can follow these steps: ### Step 1: Understand the Concept of Basicity Basicity refers to the ability of a substance to accept protons (H⁺ ions) or donate electron pairs. In the case of metal hydroxides, basicity is often related to the ionic character of the metal-hydroxide bond. **Hint:** Remember that basicity can be influenced by the metal's ionic size and the covalent character of the hydroxide. ### Step 2: Consider the Lanthanide Contraction ...
