Question

Dry hcl gas does not change the. color of dry litmus paper .why???​

Answer 1

Answer:

The acidic properties of a element is given by h+ ions.

in the dry hcl gas the molecules of hydrogen and chlorine doesn't break into ions as it is necessary because the concentration of h ions is proportional to acidity so litmus cannot identify it.

Answer 2

Answer:

Dry HCl gas does not change the color of dry litmus paper because dry HCl is nither acidic nor basic, it's neutral.

Dry HCL it does not dissociate to give H+ ions. Acids dissociate to give ions only in the aqueous solution. In this, HCL is not in the aqueous form nor the litmus paper is wet, so the colour of the litmus paper does not change.
