A solvent is a substance that can dissolve other substances, resulting in a solution. It’s the component of a solution that exists in the greatest amount. For instance, in a sugar and water mixture, water is the solvent and sugar is the solute (the substance that is dissolved). Solvents are often liquid but can also exist in the form of a gas or solid. They are fundamental in various fields like chemistry, pharmacology, and a host of different industries like paints, plastics, and cleaning.
1. What are the types of solvents?
Solvents are classified into two main types: polar and nonpolar. Polar solvents have molecules with electrical charges, and they can dissolve other polar substances like salts. Examples include water and alcohol. Nonpolar solvents don’t have a net electrical charge, making them ideal for dissolving nonpolar substances like oils or fats. Examples include hexane and benzene.
2. What is a universal solvent?

Water is often called a “universal solvent” because it can dissolve more substances than any other liquid. This is due to its polar nature, which allows it to interact with a wide range of molecules.
3. How do solvents influence chemical reactions?
Solvents can play a large role in chemical reactions. They can help control the rate of reaction, provide a medium for chemical interaction, and influence the direction of the reaction. For instance, certain reactions only occur in specific solvents.
4. Are solvents harmful?
While some solvents like water are perfectly safe, others can be harmful or dangerous. For example, organic solvents, frequently used in industries like dry cleaning or paint manufacturing, can be toxic or even carcinogenic. Always handle solvents with care, following safety guidelines.
5. What are solvent uses in everyday life?
Solvents have many everyday uses. They can be found in a variety of household products like cleaning agents, paint, and nail polish remover. In the medical field, they’re used to manufacture medicines. Additionally, they’re used in many industrial applications.
