Substances that are insoluble in water include sand, oil, wax, and most plastics. These materials do not dissolve because their molecules are either non-polar or they have large, complex molecules that water cannot break down.

FAQs & Answers

  1. What types of substances are typically insoluble in water? Common substances that are insoluble in water include sand, oil, wax, and most plastics.
  2. Why are some substances insoluble in water? Substances are often insoluble in water because their molecules are either non-polar or consist of large, complex structures that water molecules cannot effectively break down.
  3. Does temperature affect the solubility of substances in water? Yes, temperature can impact solubility; although many substances remain insoluble, heating water can increase the solubility of certain solids and gases.
  4. Can you list examples of polar and non-polar substances? Polar substances include sugar and salt, which dissolve well in water, while non-polar substances include oil and wax, which do not dissolve in water.
