Part D is an important section of the 2nd PUC Chemistry Exam 2023, as it carries a weightage of 15 marks. This section consists of questions that are relatively easy to score, provided the student has a good understanding of the concepts and has prepared well. Here are some of the important Part D questions that students should focus on:

1. Define the term ‘pH’ and explain its significance in chemistry.

This is a basic question that tests the student’s understanding of the concept of pH. The answer should include a definition of pH as the measure of acidity or basicity of a solution on a scale of 0-14, where pH 7 is neutral, pH<7 is acidic, and pH>7 is basic, as well as an explanation of its significance in chemical reactions, such as the effect on the rate of reaction and the formation of salts.

2. Explain the principle and working of a potentiometer.

This question tests the student’s understanding of the working of a potentiometer, which is a device used to measure the potential difference between two points in a circuit. The answer should include an explanation of the principle of the potentiometer, how it works, and its applications in various fields.

3. Explain the concept of activation energy and its role in chemical reactions.

This question tests the student’s understanding of the concept of activation energy, which refers to the minimum amount of energy required for a chemical reaction to occur. The answer should include an explanation of the role of activation energy in chemical reactions, the factors that affect it, and its relation to the rate of reaction.

4. Write the chemical equation for the reaction between calcium carbonate and hydrochloric acid.

This is a straightforward question that tests the student’s knowledge of chemical equations. The answer should include the balanced chemical equation for the reaction, along with the products formed and any other relevant details.

5. Explain the properties and uses of ozone.

This question tests the student’s understanding of the properties and uses of ozone, which is a gas with powerful oxidizing properties. The answer should include an explanation of the properties of ozone, its applications in various fields, and the environmental issues associated with its use.

In conclusion, Part D of the 2nd PUC Chemistry Exam 2023 contains relatively easy-to-score questions that can help students boost their overall scores. By focusing on important topics and concepts, students can ensure that they are well-prepared for this section of the exam.
