Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Permanganate titrations are not performed in presence of hydrochloric acid. Reason R: Chlorine is formed as a consequence of oxidation of hydrochloric acid. In the light of the above statements, choose the correct answer from the options given below:

1. Both A and R are true and R is the correct explanation of A
2. Both A and R are true but R is NOT the correct explanation of A
3. A is true but R is false
4. A is false but R is true

Correct answer: Both A and R are true but R is NOT the correct explanation of A

Solution

Permanganate titrations cannot be conducted in hydrochloric acid because the acidic environment leads to the reduction of permanganate and the formation of chlorine gas, which interferes with the titration. However, the reason provided does not directly explain why permanganate titrations are avoided in this context.
