Solute
The substance that gets dissolved in a liquid to form a solution, such as salt or sugar.
Solvent
The liquid in which the solute dissolves to form a solution, with water being the most common universal solvent.
Solution
A homogeneous mixture of two or more substances where the solute particles are evenly distributed throughout the solvent.
Saturated Solution
A solution in which no more solute can dissolve at a specific temperature.
Solubility
The maximum amount of a solute that can dissolve in a specific amount of solvent at a given temperature.

Board Exam Info
In Telangana (TSBSE) Class 8 science exams, this chapter typically carries around 4 to 6 marks. Common question types include defining key terms like solute and solvent, differentiating between saturated and unsaturated solutions, and short problems or reasoning questions based on the effect of temperature on solubility.
Frequently Asked Questions
Why is water called a universal solvent?
Water is called a universal solvent because it can dissolve a large number of substances, both solids and liquids, compared to any other liquid.
What happens to the solubility of a solid in water when the temperature increases?
Generally, the solubility of a solid solute in water increases as the temperature increases, meaning more solute can dissolve in hot water than in cold water.
Is a sugar solution a homogeneous or heterogeneous mixture?
A sugar solution is a homogeneous mixture because the sugar particles are uniformly distributed throughout the water and cannot be seen separately.
