NCERT Solutions for Class 12 Chemistry chapter 2 Solutions

Chapter 2 Solutions introduce many important concepts to the students like molality, molarity, mole fraction of solutions, Henry's law constant, mass percentage etc. The topics of this chapter are not only important for the class 12 CBSE Board exam but also for the various competitive exams like JEE Mains, NEET, BITSAT, VITEEE, etc. In this chapter, there are 41 questions in the chapter exercise. To develop a grip on the topic NCERT solutions for class 12 chemistry chapter 2 Solutions are designed by chemistry experts for the students.

In NCERT class 12 chemistry chapter 2 Solutions we will discuss mostly liquid solutions and their information and this chapter also covers other important concepts like types of solutions, Raoult's law and Henry's law, concentration of solutions in different units, solubility, vapour pressure of liquid solutions,  ideal and non-ideal solutions, colligative properties, determination of molar mass and abnormal molar masses.

What are the solutions?

The solutions are mixtures of two or more than two components and solutions are classified as solids, liquids, and gaseous solution. The concentration of the solution is expressed in terms of molarity, molality, mole fraction and in percentages. Types of solution discuss in NCERT class 12 chemistry chapter 2 Solutions are Gaseous solution, Liquid solution, and Solid solution.

Molality(m)=\frac{Number \:of \:moles \:of \:solute}{Weight\:of\:solvent(kg)}

Molarity(N)=\frac{Number \:of \:moles \:of \:solute}{Volume\:of\:solution(kg)}

Normality(N)=\frac{Number \:of \:gram\:equivalent \:of \:solute}{Volume\:of\:solution(kg)}
