Solution
A homogeneous mixture of two or more substances where the solute is uniformly distributed throughout the solvent.
Solute
The substance that gets dissolved in a solvent to form a solution, such as salt or sugar.
Solvent
The dissolving medium in a solution that breaks down the solute, often called the universal solvent when it is water.
Saturated Solution
A solution in which no more solute can be dissolved at a specific temperature.
Unsaturated Solution
A solution that contains less solute than it has the capacity to dissolve at a given temperature.

Board Exam Info
In the Tamil Nadu (Samacheer Kalvi) Class 8 Science board exams, this chapter typically carries around 5 to 8 marks. Questions usually include fill-in-the-blanks, true or false, definitions of solute and solvent, differentiating between saturated and unsaturated solutions, and simple numerical problems on concentration.
Frequently Asked Questions
What is the difference between a solute and a solvent?
A solute is the substance that dissolves (like sugar), while the solvent is the liquid that does the dissolving (like water).
Why is water called the universal solvent?
Water is called the universal solvent because it has the ability to dissolve more substances than any other liquid.
How does temperature affect solubility?
Generally, increasing the temperature increases the solubility of solid solutes in a liquid solvent, meaning more solute can dissolve.
