316357 Chlorine is prepared in the laboratory by the action of

316358 Assertion :
Chlorine undergoes disproportionation reaction in alkaline medium.
Reason :
\(\mathrm{Cl}_{2}\) is an oxidising agent.

316359 Concentrated hydrochloric acid when kept in open air sometimes produces a cloud of white fumes. The explanation for it is that

316360 Assertion :
\(\mathrm{NaCl}\) reacts with concentrated \(\mathrm{H}_{2} \mathrm{SO}_{4}\) to give colourless fumes with pungent smell. But on adding \(\mathrm{MnO}_{2}\) the fumes become greenish yellow.
Reason :
\(\mathrm{MnO}_{2}\) oxidises \(\mathrm{HCl}\) to chlorine gas which is greenish yellow.
