Question

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.

• A. A is false but R is true
• B. Both A and R are true but R is NOT the correct explanation of A
• C. Both A and R are true and R is the correct explanation of A
• D. A is true but R is false

Answer 1

The correct option is C Both A and R are true and R is the correct explanation of A

$HCl$ is not used in the process of titration because it reacts with the $\left(KMn{O}_4\right)$ that is used in the process and gets oxidized.
$2KMn{O}_4+16HCl\to 2MnC{l}_2+2KCl+8H_{2}O+C{l}_2$
