PSEB 10th Class Science Chapter 2 Key Concepts in Acids, Bases, and Salts

Before diving into the questions, let’s briefly summarize the essential concepts:

  • Acids: Substances that release hydrogen ions (H⁺) in aqueous solutions. Common examples include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄).
  • Bases: Substances that release hydroxide ions (OH⁻) in solution. Sodium hydroxide (NaOH) is a typical base.
  • Salts: Formed when an acid reacts with a base, resulting in a neutralization reaction.

PSEB 10th Class Science Chapter 2 Previous Year Questions and Answers

Question 1: What is the pH of a neutral solution?

Answer: The pH of a neutral solution is 7. This indicates that the concentration of hydrogen ions (H⁺) is equal to that of hydroxide ions (OH⁻).

Question 2: Why do HCl and HNO₃ show acidic behavior in aqueous solutions while glucose does not?

Answer: HCl and HNO₃ dissociate in water to release H⁺ ions, which are responsible for acidity. In contrast, glucose does not dissociate to release H⁺ ions in solution; hence, it does not exhibit acidic behavior.

Question 3: Describe the reaction between an acid and a metal carbonate.

Answer: When an acid reacts with a metal carbonate, it produces a salt, water, and carbon dioxide gas. For example:

Question 4: What happens when an acid reacts with a base?

Answer: The reaction between an acid and a base is called neutralization. It produces salt and water. For example:

Question 5: How can you identify an acidic solution using litmus paper?

Answer: An acidic solution turns blue litmus paper red. If you have red litmus paper, it will remain red in an acidic solution.
