**Question**: Which ligand is most likely to stabilize a metal in a low oxidation state?

- ○ H₂O
- ○ NO
- ○ I⁻
- ○ NH₃

This multiple-choice question examines the ability of different ligands to stabilize metals in low oxidation states. Students are asked to evaluate the properties of the given ligands: water (H₂O), nitric oxide (NO), iodide (I⁻), and ammonia (NH₃), and determine which is most effective in stabilizing metal ions with lower oxidation numbers. Understanding the electron-donating abilities and overall stability enhancement of these ligands is key to answering this question.

**Consider this reaction:** CH₃HgI + HCl ⇌ CH₃HgCl + HI

**Which is the correct prediction and explanation about the equilibrium constant, K, for this reaction?**

- ○ K > 1, because Cl is a harder base than I.

- ○ K < 1, because I is a harder base than Cl.

- ○ K < 1, because Cl is a harder base than I.

- ○ K > 1, because I is a harder base than Cl.
