U4, L2 Soulents and Solvents

Definitions:

• Solute: The substance that is dissolved in a solution. It can be a solid, liquid, or gas.

• Solvent: The substance that dissolves the solute, usually present in greater amount. It is typically a liquid.

Examples:

• In saltwater, salt is the solute and water is the solvent.

• In sugar dissolved in tea, sugar is the solute, and tea is the solvent.

Properties:

• Solutes can affect the properties of solvents, such as boiling and freezing points.

• The concentration of a solution refers to the amount of solute present in a given quantity of solvent.

Types of Solutions:

• Unsaturated: A solution that can dissolve more solute at a given temperature.

• Saturated: A solution that contains the maximum amount of solute that can be dissolved at a given temperature.

• Supersaturated: A solution that contains more solute than is normally possible at a given temperature, often achieved by changing conditions.

Importance in Chemistry:

• Understanding solutes and solvents is crucial for solutions’ behavior in chemical reactions, biological processes, and industrial applications.
