Why does dry HCl gas not change the colour of the dry litmus paper?
Asked by saee.suryavanshi | 05 Aug, 2019, 01:20: PM
Expert Answer
The acidic behaviour of HCl is due to formation of Hydrogen ions
Dry HCl does not dissosciate to form H+ ions and hence does not show acidic properties viz changing the colour of blue litmus to red
