Question

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

Answer 1

Answer:

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 aqueous form nor litmus paper is wet, so thecolour of litmus paper does not change.
