Instructor introduces the session and outlines the importance of the topic for board exams 2019.
Emphasis on important previous year questions and critical topics like vapor pressure, boiling point elevation, freezing point depression, molecular mass, and Van't Hoff factor.
What is a Solution?
Definition: A homogeneous mixture of two or more substances.
Homogeneous mixtures: Uniform composition throughout (e.g., salt in water).
Heterogeneous mixtures: Not uniform; different phases are visible (e.g., sand in water).
Components of a Solution
Solute: Substance being dissolved (e.g., sugar in water).
Solvent: Substance doing the dissolving (e.g., water).
Example: In sugar water, water is the solvent, and sugar is the solute.
Types of Solutions
Binary Solutions: Two components; solute and solvent.
Example: Brass (copper + zinc) is an alloy, a type of solution where both components are solid.
Table example: Displays the state of solute and solvent to describe the type of solution (e.g., gas in liquid, solid in liquid).
