To determine the action of the given substances on litmus paper, we need to understand how litmus paper reacts to acidic and basic solutions. Litmus paper turns red in acidic solutions and blue in basic solutions. Let's analyze each substance one by one. ### Step-by-Step Solution: 1. **Dry HCl Gas**: - Dry HCl gas does not contain H⁺ ions in its gaseous form. Therefore, it does not exhibit acidic properties until it is dissolved in water. - **Action on Litmus Paper**: No change (remains the same). ...
