Question

why is hci gas unable to change the color of dry blue litmus paper? what happens if litmus paper is moistened ​

Answer 1

Answer:

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

if litmus paper is moistoned to a particular amount then blue litmus paper will surely turn red

thank you
