What happens when blue litmus paper is dipped into chlorine water?

Question

Verified by Toppr

Answer 1

Chlorine water on standing initially gives an amount of hypochlorous acid $H O C l$ . So, the color of the litmus paper will change from blue to red. After some time $H C l$ and $H C l O_{3}$ will be produced and both of them are acidic.

$C l_{2} + H_{2} O ⟶ H C l O_{3} + H C l$
Hence, option $A$ is correct.

Answer 2

Chlorine water on standing initially gives an amount of hypochlorous acid

H O C l

. So, the color of the litmus paper will change from blue to red. After some time

H C l

and

H C l O_{3}

will be produced and both of them are acidic.

C l_{2} + H_{2} O ⟶ H C l O_{3} + H C l

Hence, option

A

is correct.
