NCERT class 10 science chapter 2 – “Acids, Bases, and Salts” discusses reactions of acids and bases, how acids and bases cancel out each other’s effects and many more interesting things that we use and see in our day-to-day life. Practice multiple-choice questions (MCQs) to prepare for the objective questions for the CBSE Board Exams. We have provided Class 10 MCQ Questions on the “Acids, Bases and Salts” along with detailed explanations. CBSE is putting more focus on MCQs as they help in understanding the concepts thoroughly.
MCQs are very different from subjective questions so practicing and understanding how to arrive at correct answers in MCQs is very important. Students should practice all the MCQs with answers provided to review the key concepts and familiarize themselves with the types of questions that might come in the board exam.

Summary for NCERT class 10 science chapter 2 – “Acids, Bases and Salts”
- Acid-base indicators are dyes or mixtures of dyes which are used to indicate the presence of acids and bases.
- Acidic nature of a substance is due to the formation of H+ (aq) ions in solution. Formation of OH– (aq) ions in solution is responsible for the basic nature of a substance.
- When an acid reacts with a metal, hydrogen gas is evolved and a corresponding salt is formed.
- When a base reacts with a metal, along with the evolution of hydrogen gas a salt is formed which has a negative ion composed of the metal and oxygen.
- When an acid reacts with a metal carbonate or metal hydrogencarbonate, it gives the corresponding salt, carbon dioxide gas and water.
- Acidic and basic solutions in water conduct electricity because they produce hydrogen and hydroxide ions respectively.
- The strength of an acid or an alkali can be tested by using a scale called the pH scale (0-14) which gives the measure of hydrogen ion concentration in a solution.
- A neutral solution has a pH of exactly 7, while an acidic solution has a pH less than 7 and a basic solution a pH more than 7.
- Living beings carry out their metabolic activities within an optimal pH range.
- Mixing concentrated acids or bases with water is a highly exothermic process.
- Acids and bases neutralise each other to form corresponding salts and water.
- Water of crystallisation is the fixed number of water molecules present in one formula unit of a salt.
- Salts have various uses in everyday life and in industries.
