AI Generated Solution

To find the coordination number and oxidation state of the metal in each of the given complexes, we will analyze each complex step by step. ### Solution: 1. **Complex: [AgCl₂]⁻** - **Coordination Number**: The coordination number is the number of ligands attached to the central metal atom. Here, Ag is coordinated to 2 Cl ligands. Therefore, the coordination number is **2**. - **Oxidation State**: Let the oxidation state of Ag be \( x \). The charge from 2 Cl ligands (each with a -1 charge) contributes -2. The overall charge of the complex is -1. \[ ...
