**Solubility Product Constants (25 °C)**

The table below lists the solubility product constants (\(K_{sp}\)) for various compounds at a temperature of 25 °C. These constants provide insight into the solubility of the compounds in water.

| Compound (s) | \(K_{sp}\)        |
|--------------|-------------------|
| BaF₂         | \(2.4 \times 10^{-5}\) |
| CuCl(s)      | \(1.9 \times 10^{-7}\) |
| PbF₂         | \(4.0 \times 10^{-8}\) |
| AgCl(s)      | \(1.6 \times 10^{-10}\) |
| FeCO₃        | \(2.1 \times 10^{-11}\) |
| Mn(OH)₂      | \(2.0 \times 10^{-13}\) |
| AuCl(s)      | \(2.0 \times 10^{-13}\) |
| Cd(OH)₂      | \(1.2 \times 10^{-14}\) |

### Explanation:

- **BaF₂** has a relatively higher solubility product, indicating greater solubility compared to the other compounds listed.
- **CuCl(s)** and **PbF₂** display moderate solubility with lower \(K_{sp}\) values.
- **AgCl(s)**, **FeCO₃**, and **Mn(OH)₂** have significantly lower solubility as indicated by their \(K_{sp}\) values.
- **AuCl(s)** and **Cd(OH)₂** possess very low solubility, as reflected by their \(K_{sp}\) values.

These values are critical for predicting and understanding the solubility behavior of these compounds in various chemical processes and environmental contexts.
