An example of substances that are soluble and insoluble: Salt (sodium chloride) is soluble in water, dissolving completely to form a saline solution. On the other hand, sand (silicon dioxide) is insoluble in water, remaining as separate particles even when mixed. Understanding these properties helps in various practical applications, from cooking to construction.

FAQs & Answers

  1. What are some common examples of soluble substances? Common examples of soluble substances include salt (sodium chloride) and sugar (sucrose), both of which dissolve in water to form homogeneous solutions.
  2. What are some examples of insoluble substances? Examples of insoluble substances include sand (silicon dioxide), oil, and wood, which do not dissolve in water and remain as separate entities when mixed.
  3. What factors affect solubility? Factors that affect solubility include temperature, the nature of the solute and solvent, and pressure. For instance, increasing temperature typically increases the solubility of solids in liquids.
  4. Why is understanding solubility important? Understanding solubility is crucial for various applications, including cooking, pharmaceuticals, and environmental science, as it influences how substances interact in different scenarios.
