The physical properties of a solvent include its ability to dissolve a solute, forming a solution. Solvents can be characterized by their boiling and melting points, density, viscosity, and polarity. Important is the solvent's polarity, which determines its effectiveness in dissolving different types of solutes. Water, being a highly polar solvent, is excellent at dissolving many substances, which is why it's often referred to as the 'universal solvent'.
FAQs & Answers
- What determines a solvent's ability to dissolve substances? A solvent's ability to dissolve substances is primarily determined by its polarity, which affects how well it can interact with and break down different solutes.
- Why is water called the universal solvent? Water is called the universal solvent because of its high polarity, which enables it to dissolve a wide variety of substances more effectively than most other solvents.
- What are the main physical properties used to characterize solvents? Solvents are characterized by their boiling and melting points, density, viscosity, and polarity, all of which influence their performance in dissolving solutes.
- How does the viscosity of a solvent affect its use? Viscosity indicates the thickness or flow resistance of a solvent, affecting how easily it can mix with solutes and penetrate materials during dissolution.
