Chapter 1 Solutions

In Lecture 1 of the Arambh Series, we begin with a strong foundation of Chapter 1 – Solutions. This session introduces students to the concept of solutions in chemistry, their importance in real life, and the basic terms like solute, solvent, and types of solutions.

Through relatable examples — like salt in water, air we breathe, and soft drinks — the lecture helps students understand:

• What is a solution?

• Why solutions are homogeneous mixtures

• Real-life importance of studying solutions

• Classification of solutions based on states of solute and solvent

This lecture sets the tone for the entire chapter and builds conceptual clarity in a simple and engaging way.
