Solvents are substances used to dissolve, suspend, or extract other materials without chemically changing them. They are classified into two main categories: polar (e.g., water, alcohol) and non-polar (e.g., toluene, benzene). Polar solvents have molecules with a significant electronegativity difference, enabling them to dissolve ionic and other polar substances. Non-polar solvents, on the other hand, dissolve non-polar compounds due to similar intermolecular forces. Their properties, such as boiling point, polarity, and solubility, dictate their applications in various industries including pharmaceuticals, manufacturing, and research.

FAQs & Answers

  1. What is the difference between polar and non-polar solvents? Polar solvents have molecules with significant electronegativity differences, allowing them to dissolve ionic and polar substances, while non-polar solvents dissolve non-polar compounds due to similar intermolecular forces.
  2. Why are solvent properties important in industrial applications? Properties like boiling point, polarity, and solubility determine how solvents can be used effectively in industries such as pharmaceuticals, manufacturing, and research.
  3. Can solvents chemically change the substances they dissolve? No, solvents dissolve, suspend, or extract other materials without chemically altering their composition.
