Insoluble substances are those that do not dissolve in a particular solvent. In science grade 6, common examples include sand in water, oil in water, and chalk in water. When you add these substances to water, they remain separate and do not form a solution. Understanding insolubility helps explain why certain mixtures can be easily separated by filtration or other methods.

FAQs & Answers

  1. What are examples of insoluble substances? Common examples of insoluble substances include sand, oil, and chalk when mixed with water. These materials do not dissolve and remain separate.
  2. Why are some substances insoluble? Substances are considered insoluble because their molecular structure does not allow them to interact with certain solvents, preventing dissolution.
  3. How can insoluble substances be separated from liquids? Insoluble substances can often be separated from liquids using methods such as filtration, where solid particles are trapped while the liquid passes through.
  4. What does it mean for a substance to dissolve? To dissolve means that a substance (the solute) is evenly distributed in another substance (the solvent), forming a solution. Insoluble substances do not undergo this process.
