Three examples of insoluble salts are silver chloride (AgCl), barium sulfate (BaSO4), and lead(II) iodide (PbI2). These salts do not dissolve significantly in water, which makes them useful in various chemical applications such as precipitation reactions and gravimetric analysis.

FAQs & Answers

  1. What is an insoluble salt? An insoluble salt is a salt that does not dissolve significantly in water, resulting in a solid precipitate in a solution.
  2. Why are insoluble salts important in chemistry? Insoluble salts are important in chemistry for applications such as precipitation reactions, gravimetric analysis, and as a method for purifying compounds by removing soluble impurities.
  3. Can you name other examples of insoluble salts? Yes, in addition to silver chloride, barium sulfate, and lead(II) iodide, other examples include calcium carbonate (CaCO3) and mercurous chloride (Hg2Cl2).
  4. How can the solubility of a salt be determined? The solubility of a salt can be determined through experiments that involve mixing it with water and observing whether it dissolves, or by consulting solubility rules in chemistry.
