Reason (R): The acidic ingredient in the paste protects tooth from decay.
(a) Both assertion (A) and reason (R) are true and (R) is correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true, but reason (R) is false.
(d) Assertion (A) is false, but reason (R) is true.
Difficulty Level: Difficult
Ans. Option (c) is correct.
Explanation: The nature of the tooth paste commonly used is basic. It neutralise any acid released from the sugary’ items which we eat and protects from tooth decay.
Q.2. Assertion (A): Salt may be acidic, basic or neutral in nature.

Frequently Asked Questions (FAQs) on Acids Bases and Salts Assertion Reason Questions
Q1: What are Assertion-Reason questions?
A1: Assertion-Reason questions are a format used in CBSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students must determine whether each statement is true or false and whether the Reason correctly explains the Assertion.
Q2: How do Assertion-Reason questions differ from other question types?
A2: Unlike multiple-choice questions, Assertion-Reason questions require students to analyze the relationship between two statements. It involves critical thinking to understand how the statements are logically connected.
Q3: What steps should I follow to correctly answer Assertion-Reason questions?
A3: Follow these steps:
Read both statements carefully. Understand the meaning of each statement.
Determine the truth value of each statement. Decide if each statement is true or false independently.
Analyze the relationship. If both statements are true, determine whether the Reason (R) correctly explains the Assertion (A).
Choose the correct option. Based on your analysis, select the appropriate answer from the given options.
Q4: What options are typically provided for Assertion-Reason questions?
A4: The typical options are:
A. Both A and R are true, and R is the correct explanation of A.
B. Both A and R are true, but R is not the correct explanation of A.
C. A is true, but R is false.
D. A is false, but R is true.
Q5: What should I check to determine if the Reason correctly explains the Assertion?
A5: Ensure that the Reason provides a logical and direct explanation for the Assertion. The Reason should clarify or justify the Assertion, showing a clear cause-and-effect relationship.
Q6: How can I improve my skills in answering Assertion-Reason questions?
A6: Practice is the key. Focus on understanding concepts thoroughly rather than rote memorization. Analyze how different facts and concepts interrelate to enhance your ability to correctly answer these questions.
Q7: Where can I find more assertion-reason questions on acids, bases and salts for practice?
A7: We offer a collection of assertion-reason questions for all classes and subject on our website. These questions are designed to help students practice critical thinking skills and reinforce their understanding of scientific concepts. Visit our website to access these questions and enhance your learning experience. There is another website Physics Gurukul that offers a large collection of assertion reason questions for all classes and subjects.
Q8: What are common mistakes to avoid when answering Assertion-Reason questions?
A8: Common mistakes include:Not reading the statements carefully and missing key details.
Assuming the Reason explains the Assertion without checking the logical connection.
Confusing the order or relationship between the statements.
Overthinking and adding information not provided in the question.
Q9: How important is contextual understanding in Assertion-Reason questions?
A9: Contextual understanding is crucial. It helps you determine whether the Reason accurately and logically explains the Assertion within the context of the scientific principles involved.
Q10: Can you provide some tips for answering assertion reason questions for class 7 science correctly?
A10: Here are some tips that will help you to answer correctly:
Understand the Concepts: A thorough understanding of scientific concepts is essential. This will help you determine the truth value of both the Assertion and the Reason.
