Assetion : Permanganate titrations is not carried out in presence of hydrochloric acid.
Reason : Hydrochloric acid is oxidised to chlorine.

Options

A. Statement-1 is true , Statement-2 is true and Statement-2 is correct explanation for Statement-1
B. Statement-1 is true, Statement-2 is True and Statement-2 is Not correct explanation for statement-1
C. Statement-1 is true, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

A

Explanation

Permanganate titration is not carried out in presence of `HCl` because it may oxidised some of the `HCl` to `Cl_(2)` gas according to the following chemical reaction ,`2MnO_(4)^(-)+10Cl^(-)to2Mn^(2+)+8H_(2)O+5Cl_(2)` hence we do not get the correct end point for the given titration.
