Lead(II) bromide, or PbBr2, is only slightly soluble in water. When it comes in contact with water, it does not dissolve well due to the strong ionic bonds holding the lead and bromide ions together.
The solubility of PbBr2 in water is indeed low, typically around 0.0067 g per 100 mL at room temperature. This means that while it can dissolve to a small extent, the majority of the compound remains as a solid.
This low solubility is an important consideration in various fields such as environmental science and materials engineering, where the behavior of lead compounds in aqueous solutions can impact everything from toxicity potential to the design of chemical processes.
