प्रश्न
Explain why dry hydrogen chloride gas does not affect a dry strip of blue litmus paper but it turns red in the presence of a drop of water.
उत्तर
A dry strip of blue litmus paper is unaffected by dry \[\ce{HCl}\] gas due to the gas's non-acidic nature. In the presence of a drop of water, \[\ce{HCl}\] gas dissolves and produces hydrochloric acid, which turns blue litmus paper red.
