NCERT Solutions for Class 11 Chemistry Chapter 1: Important Topics

Chemistry is very important as it encompasses every sphere of life. Chemists study the properties and structure of substances and the changes undergone by them. All substances contain matter, which can exist in three states – solid, liquid or gas. In this chapter, students learn about the nature of material and chemical laws of combination. This chapter helps students build a strong base for Chemistry. It will help students know about the atomic and molecular masses along with the mole concept, chemical reactions, and molecular formula.

Thus, practical questions included in the chapter will help students understand the concepts better. Students will be introduced to the Law of Conservation of Mass, Law of Definite Proportions, Law of Multiple Proportions, International System of Units, Weights and Measures, etc. This is one of the basic chapters in Chemistry and is a low weightage chapter from the exam point of view. Understand the entire chapter thoroughly before attempting to solve the questions.

NCERT Solutions for Class 11 Chemistry Chapter 1: Points to Remember

We have provided some important points that are covered in NCERT Class 11 Chemistry Chapter 1 to help students in their exam preparations. Refer to the list below:

  • In chemical classification, the matter is classified as mixtures, compounds and elements.
  • A homogeneous mixture has uniform composition and properties throughout while a heterogeneous mixture’s composition and properties are not uniform throughout.
  • The law of conservation of mass states that the total mass of all the products in a chemical reaction is the same as that of all the reactants present before the reaction.
  • The law of definite proportions states that a chemical compound is always made up of the same elements combined together in a fixed proportion by mass.
  • The law of multiple proportions states that when two elements combine to form two or more compounds, then masses of one of the elements which combine with a fixed mass of the other bear a simple ratio to one another.
  • The Gay-Lussac’s law of combining volumes states that volume of gaseous reactants and products bear a simple ratio to one another when measured under identical conditions of temperature and pressure.
  • Avogadro’s law states that equal volumes of all gases under similar conditions of temperature and pressure contain equal numbers of molecules.
