Chemistry Class 12 NCERT Solutions and Study Guide
Everything around us is made up of atoms and molecules, we can see chemistry everywhere. Chemistry has evolved into a discipline with a wide range of applications. There is a lot of variation between chemistry and other fields of research and science. Chemistry is one of the most significant fields of study. Chemistry is the study of matter’s constituents, such as atoms, molecules, and ions, as well as their properties, structure, behaviour, and interactions. It has a wide range of uses in everyday life. The food we consume is merely a concoction of different chemicals. Chemistry plays an important role in the processing of food, as well as in the preparation of food. Take, for example, tomatoes grown on farms. To increase tomato yield, farmers use fertilisers and crop-protection chemicals such as insecticides and pesticides. The ripe tomatoes are then transported to food processing factories, where they are processed into a finished product, such as ketchup, and various ingredients, such as flavouring agents and chemical additives, are applied at various stages of food processing depending on chemistry.
Cleaning, bathing, and washing all require the use of detergents and soaps. They’re made up of a variety of chemicals that have cleaning properties. Saponification of fatty acids is used in the chemical industry to make them. Chemicals developed in the pharmaceutical industry are used to make drugs. For pharmacists and physicians, chemistry knowledge is important. Chemicals are also used to destroy bacteria during sterilisation and disinfection. Chemistry aids pharmacists in comprehending biochemical mechanisms in the human body. Wool, silk, jute, cotton, flax, glass fibre, polyester, acrylic, nylon, and other raw materials are used in the garment industry. These materials are made into useful finished goods such as clothing, containers, carpets, chairs, towels, flags, nets, and balloons, among other things.
Raw materials are exposed to a variety of chemical processes during this transformation. Building efficiency is governed by chemistry. Building materials play an important role in improving building efficiency. Reflective roofs are made possible by coating chemicals such as acrylics, silicones, and urethane, which reduce heat transfer.
With so many practical applications of chemistry knowledge in everyday life, focusing solely on the school curriculum is insufficient. You must be able to complete NCERT in order to concentrate on developing an in-depth understanding of chemistry and studying. Thus, Extra marks saves the day by supplying you with the best Chemistry Class 12 NCERT Solutions, allowing you to finish your syllabus ahead of schedule and concentrate on the topic as a foundation for life with a deep conceptual understanding. Now is the time to download the Extra marks app and start searching for the best Chemistry research materials available. Few examples of chapters in that are comprehensively discussed in the NCERT Solutions are as follows:
Chapter 1: The Solid State
The solid state is the subject of this chapter. There are 11 subtopics in total. This chapter discusses crystalline and amorphous solids, as well as solid defects. It starts with a detailed explanation of the unit cell and then progresses to the solid state. The solutions are written using the NCERT text as a guide. It explains the concepts in the textbook and aids students in reinforcing the fundamentals.
Chapter 2: Solutions
The second chapter discusses the different types of solutions and their characteristics. Raoult’s law, concentration of solutions, vapour pressure of liquid solutions, irregular molar masses, and colligative properties are among the topics covered. The back and in-chapter activities are designed to reinforce concepts, while the solutions assist students in doing so. This chapter is worth a total of 5 points on the Board test.
Chapter 3: Electrochemistry
The electrochemical cell is the subject of this chapter. The galvanic and electrolytic cells are also taught to students. The standard potential of the cell, the Gibbs energy of cell reaction, and the relationship with the equilibrium constant are all explained in this chapter. The Kohlrausch Law and its implementations will be taught to the students.
Chapter 4: Chemical Kinetics
The kinetics, or rate of a reaction, is the subject of this chapter. The factors influencing the rate of a reaction, the integrated rate equation, Pseudo First Order reactions, and the collision theory of chemical reactions are among the topics discussed. This chapter is also accountable from the engineering and medical sciences perspectives.
