Dry HCL is not acidic in nature...because if it is not dissolved in water...the HCL (dry) would not disassociate into ions...i.e H^+ ion would not get separated from Cl^-ion... To change the colour of litmus from blue to red...we have to dissolve HCL (dry) into water

We know that the colour of litmus paper is changed by H + ions because of acid.
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 the colour of litmus paper does not change.
