Question

why dry HCL does not changes the colour of litmus paper?​

Answer 1

Answer and Explanation:

To change the colour of blue litmus paper to red, there must be a presence of acid. Dry HCl gas is not acidic because water is required for the dissociation of HCl into H+ and Cl-. Therefore, dry HCl gas is not acidic and will not change the colour of dry blue litmus paper.

It is hydrogen ions (H+) that gives acidic properties.

To change the colour of blue litmus paper to red, there must be a presence of acid. Dry HCl gas is not acidic because water is required for the dissociation of HCl into H+ and Cl-.
