Answer: Hg₂I₂ is insoluble in water. It has low solubility and forms a yellow precipitate with water.

Hg₂I₂ is generally considered insoluble in water. It has low solubility and forms a yellow precipitate when mixed with water while other compounds like BaS, (NH₄)₂CO₃, and MgSO₄ are soluble in water.
