Answer:
1. Distilled water is pure form of water which do not contain any solute in it. Therefore it cannot conduct electricity because it does not contain ions while rain water contains dissolved salts and acids which dissociates in ions and conducts electricity.
2. 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.
