Question

Chlorine gas bleaches moist litmus paper.

• A. True
• B. False

Answer 1

The correct option is A True

When chlorine reacts with water (moist) the following reaction takes place:

$C{l}_2$ $+$ $H_{2}O$ $⟶$ $HCl$ $+$ $HClO$

Due to the formation of HCl, it will initially turn blue litmus to red.

But due to the reaction

$HClO$ $⟶$ $HCl$ $+$ $\left[O\right]$

nascent oxygen

Forms nasient oxygen which is an oxidizing agent, bleaching action will take place and finally it will bleach the litmus paper.
