* Solvent: A substance, usually a liquid, that dissolves another substance. Common examples include water, alcohol, and acetone.

* Solute: The substance being dissolved.

* Solution: A homogeneous mixture formed when the solute dissolves in the solvent.

Key Points:

* Solubility: The degree to which a solute dissolves in a particular solvent at a given temperature.

* Factors Affecting Solubility: Temperature, pressure, and the nature of the solute and solvent all play a role in solubility.

* Examples: Sugar is soluble in water, creating a sugary solution. Oil is not soluble in water, forming two separate layers.

In simpler terms:

Imagine you have a cup of water (solvent) and you add a spoonful of sugar (solute). If the sugar dissolves and disappears into the water, it's soluble. If it doesn't dissolve, it's considered insoluble.
