Concentrated hydrochloric acid when kept...

Concentrated hydrochloric acid when kept in open air sometimes produces a cloud of white fumes. The explanation for it is that :

A

due to strong affinity for water, concentrated hydrochloric acid pulls moisture of air towards itself. This moisture forms droplets of water and hence the cloud.

B

concentrated hydrochloric acid emits strongly smelling HCl gas all the time

C

oxygen in air reacts with the emitted HCl gas to form a cloud of chlorine gas

D

strong affinity of HCl gas for moisture in air results in formation of droplets of liquid solution which appears like a cloudy smoke.

Text Solution

Verified by Experts

The correct Answer is:
D
Concentrated hydrochloric acid produces vapours of HCl. As HCl has strong affinity for moisture it results in the formation of droplets of liquid solution which appears like a cloudy smoke.
