Universal Solvent: Explanation

In chemistry, a universal solvent is a substance that has the ability to dissolve a wide range of different solutes. The most well-known universal solvent is water. Water is considered a universal solvent because it is capable of dissolving a variety of substances due to its unique chemical properties.

Properties of Water as a Universal Solvent:

1. Polarity: Water is a polar molecule, meaning it has a slightly positive end and a slightly negative end. This allows it to interact with and dissolve other polar and ionic substances.
2. Hydrogen Bonding: Water molecules can form hydrogen bonds with other polar molecules, helping to break them apart and dissolve them.
3. High Dielectric Constant: Water has a high dielectric constant, which means it is very effective at separating and dispersing charged particles, making it an effective solvent for ionic compounds.

Examples of Substances Dissolved by Water:

Water can dissolve many substances, including:

• Sugar
• Salt
• Acids and Bases
• Many organic compounds
• Some gases, such as oxygen and carbon dioxide
