Question

Chlorine gas turns moist potassium bromide paper red.

• A. True
• B. False

Answer 1

The correct option is A True

When chlorine gas reacts with potassium bromide, the following reaction takes place

Cl${}_2$ + 2KBr $\to$ 2KCl + Br${}_2$

Due to the formation of bromide, the colour will change to red.

Br${}_2$ is red in colour.

Hence chlorine gas turns moist bromide paper red.
