Chemistry: Chapter 9- The Amazing World of Solutes, Solvents, and Solutions

Solute

The substance that dissolves.

Solvent

The substance in which the dissolving occurs.

Solution

The substance formed when the solute dissolves in the solvent.

Unsaturated solution

The substance in which more solute can be dissolved at a given temperature.

Saturated solution

The solution in which more solute cannot be dissolved at a given temperature.

Concentration

The amount of solute present in a fixed quantity of solution/solvent.

Dilute solution

Less amount of solute in the solvent (subjective).

Concentrated solution

More amount of solute in the solvent (Subjective).

Solubility

The maximum amount of solute that dissolves in a fixed quantity of the solvent.

Density

The mass present in a unit volume of that substance. SI Unit: Kilogram/Metre³ (kg/m³).

Relative Density

Density of any substance with respect to another substance (usually water).

Effect of Temperature on density

Density increases when temperature decreases.

Effect of pressure on density

Density of gases increases with pressure, while its effect on solids and liquids is negligible.
