Solute
The substance that gets dissolved in a liquid to form a solution, such as salt or sugar.
Solvent
The dissolving medium in which the solute dissolves, with water being the most common universal solvent.
Solution
A homogeneous mixture of two or more substances composed of a solute and a solvent.
Saturated Solution
A solution in which no more solute can be dissolved at a given temperature.
Unsaturated Solution
A solution that contains less solute than the maximum amount it can dissolve at a specific temperature.

Questions commonly include definitions of solute and solvent, differentiating between saturated and unsaturated solutions, and short numerical or conceptual application questions based on daily life examples.
Frequently Asked Questions
What is the difference between a solute and a solvent?
A solute is the substance that gets dissolved (like sugar), while the solvent is the liquid that does the dissolving (like water).
Why is water called a universal solvent?
Water is called a universal solvent because it can dissolve a wide variety of substances compared to any other liquid.
What happens when you heat a saturated solution?
When you heat a saturated solution, its capacity to dissolve solute increases, turning it temporarily into an unsaturated solution where more solute can be dissolved.
