Introduction
Solutions is the first chapter of Class 12 Physical
Chemistry and deals with the properties of solutions formed by mixing two or
more substances. This chapter covers important concepts such as types of
solutions, concentration terms, solubility, vapour pressure, and colligative
properties.
A strong understanding of solutions is essential for CBSE Board examinations
and for solving numerical and conceptual questions in competitive exams like
NEET and JEE (Main).
