Discover why no elements are always insoluble in water and explore common insoluble compounds like silver chloride and calcium carbonate.

21 views

In chemistry, no elements are always insoluble; rather, insolubility often refers to compounds. Some examples of compounds typically considered insoluble in water include silver chloride (AgCl), lead sulfate (PbSO4), and calcium carbonate (CaCO3). The solubility can change under different conditions such as temperature, pressure, and the presence of other substances.

FAQs & Answers
