Given below are two statements: One is labelled as Assertion and the other is labelled as Reason
Assertion : Permanganate titration are not performed in presence of hydrochloric acid.
Reason : 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
- Correct answerABoth and are true and is the correct explanation of
- BBoth and are true but is NOT the correct explanation of
- Cis true but is false
- Dis false but is true
Solution
Hydrochloric acid (HCl) is usually not used in the process of titration because it reacts with the indicator potassium permanganate that is used in the process. It reacts with solution and gets oxidized which further results in the liberation of chlorine gas according to the following reaction.
So, Both and are true and is the correct explanation of
Hence, the correct answer is option: 'A'.
