Yes, mixing salt and water is a physical change. The salt dissolves in the water, forming a homogeneous mixture, but no new substances are created. This process is reversible; you can retrieve the salt through evaporation.

FAQs & Answers

  1. What is a physical change? A physical change is a change in the form or appearance of a substance without creating a new substance. Examples include dissolving, melting, and freezing.
  2. Is dissolving salt in water a physical or chemical change? Dissolving salt in water is a physical change because the salt dissolves to form a homogeneous mixture without any new substances being produced.
  3. Can the salt be recovered after it dissolves in water? Yes, the salt can be recovered by evaporating the water, demonstrating that the change is reversible.
  4. What is the difference between physical and chemical changes? Physical changes alter a substance’s physical properties without changing its chemical identity, while chemical changes result in new substances with different properties.
