FAQs & Answers
- What does it mean if a substance is soluble? A soluble substance is one that dissolves in a solvent, usually water, forming a homogeneous solution.
- What are some common insoluble substances? Common insoluble substances include sand (SiO2), chalk (CaCO3), gold (Au), wax, and plastic, which do not dissolve in water.
- How can you tell if a substance is soluble or insoluble? Soluble substances dissolve completely in water forming a clear solution, while insoluble substances do not dissolve and often form a suspension or sediment.
- Why is solubility important in chemistry? Solubility determines how substances interact in solutions, which is crucial for chemical reactions, pharmaceuticals, and industrial applications.
