NCERT Solutions for Class 10 Science Chapter 1

“Chemical Reactions and Equations” is a fundamental chapter in NCERT Solutions for Class 10 Science that delves into the intricate world of chemical transformations. This chapter serves as a gateway to comprehending the underlying processes that drive changes in matter, as well as the language used to describe them.

At its core, this chapter introduces students to chemical reactions – the intricate dance of atoms and molecules that give rise to new substances with distinct properties. It starts by elucidating the concept of chemical equations, which are symbolic representations of these reactions. These equations consist of reactants (the starting substances) and products (the resulting substances), demonstrating the balance between mass and atoms in reactions.

The chapter then dives into different types of chemical reactions, such as combination reactions where elements unite, decomposition reactions where compounds break down, displacement reactions where atoms trade places, and redox reactions involving electron transfers. As students progress, they learn how to balance these equations, ensuring the conservation of mass and atoms on both sides.

Furthermore, the chapter explores the concept of oxidation and reduction, critical processes underpinning various chemical reactions. Oxidation involves the loss of electrons, while reduction involves gaining electrons. The combination of these two processes referred to as redox reactions, drives many transformations in nature.

The chapter “Acids, Bases, and Salts” in NCERT Class 10 Science delves into the fascinating world of chemical substances with distinct properties and roles in various everyday applications. This chapter serves as a fundamental introduction to the concepts of acidity, basicity, and the formation of salts, offering valuable insights into the science behind sour tastes, cleaning agents, and even the preservation of food.

Acids: Acids are substances that possess a sour taste and the ability to turn blue litmus paper red. The chapter explains that acids release hydrogen ions (H+) when dissolved in water. Examples of common acids include hydrochloric acid (HCl), found in the stomach for digestion, and citric acid, present in citrus fruits.

Bases: Bases, often referred to as alkalies, exhibit a bitter taste and have the property of turning red litmus paper blue. Bases release hydroxide ions (OH-) in aqueous solutions. Common examples include sodium hydroxide (NaOH) and ammonia (NH3).

pH Scale: The concept of the pH scale is crucial in this chapter. It measures the acidity or basicity of a solution. The scale ranges from 0 to 14, where 7 is neutral (as in pure water), values below 7 are acidic, and values above 7 are basic. The lower the pH value, the stronger the acid, and the higher the pH value, the stronger the base.

Indicators: The chapter discusses indicators, which are substances that change color based on the pH of a solution. Examples of indicators include litmus paper, phenolphthalein, and methyl orange. These indicators help identify whether a substance is acidic, basic, or neutral.

Salts: Salts are formed through the reaction between an acid and a base. This process is called neutralization. The chapter explains how the hydrogen ions from acids combine with the hydroxide ions from bases to form water, while the remaining ions combine to form salts. For instance, the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) produces sodium chloride (NaCl), commonly known as table salt.

“Heredity and Evolution” is a captivating chapter in NCERT Class 10 Science that delves into the fascinating journey of how life forms inherit traits and how species change over time. It unravels the interplay between genetics and the gradual transformation of species through the process of evolution.

Heredity refers to the passing on of traits from one generation to the next. Traits can be physical features, behaviors, or other characteristics that make each organism unique. The chapter begins by exploring Mendel’s laws of inheritance, which laid the foundation for our understanding of genetics. Mendel’s experiments with pea plants revealed how traits are inherited through genes, which are units of heredity located on chromosomes.

The concept of variation is crucial to heredity. Organisms of the same species exhibit variations due to the genetic differences inherited from their parents. This diversity is essential for the process of natural selection, a driving force of evolution. Natural selection, proposed by Charles Darwin, explains how organisms with advantageous traits survive and reproduce, passing on these traits to their offspring. Over time, these traits become more common in the population, leading to the adaptation of species to their environment.

The chapter “Light – Reflection and Refraction” in NCERT Class 10 Science delves into the fascinating behavior of light when it interacts with various surfaces, leading to phenomena like reflection and refraction. This exploration plays a pivotal role in understanding how we perceive the world around us.

Reflection: The chapter starts by discussing the reflection of light, which occurs when light rays bounce off a surface. You’ll learn about the laws of reflection – the incident ray, the reflected ray, and the normal all lie in the same plane, and the angle of incidence is equal to the angle of reflection. Mirrors, whether plane or curved, are explored, explaining how they form virtual and erect images through reflection.

Spherical Mirrors: The chapter delves into concave and convex mirrors. Concave mirrors are thicker at the edges and can form both real and virtual images based on the object’s position. Convex mirrors, on the other hand, are thinner at the edges, always producing virtual, smaller images that appear farther away.

Refraction: The chapter then transitions to refraction – the bending of light when it passes from one medium to another. This bending is due to the change in the speed of light in different media. You’ll understand Snell’s law, which quantifies how much light bends, and the concept of the refractive index, a measure of how much a medium can bend light.
