Question

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 HCI gas all the time (C) oxygen in air reacts with the emitted HCI gas to form a cloud of chlorine gas (D) strong affinity of HCI gas for moisture in air results in forming of droplets of liquid solution which appears like a cloudy smoke
