CBSE Class 10 - Chemistry - Acids, Bases and Salts - Assertion Reason Based Questions

Assertion and Reasoning based questions are a bit tricky. You should be able to distinguish whether the assertion is well connected to the reason or these are just random facts. Read both statements carefully, and check if both statements are factually or logically correct or not. If both are correct, then try to check if both are well connected to each other or not.

The questions below consist of statements of an Assertion and a Reason. Use the following key to choose an appropriate answer:

(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.

Q1: Assertion (A) : Acids are those substances which turn blue litmus solution red.

       Reason (R)    : Acids give more OH⁻ ions in aqueous solution.
