Why does dry HCI gas not change the colour of dry litmus paper?
Detailed Explanation:
Dry HCl gas does not ionize to produce H₃O⁺ (hydronium) ions because ionization requires the presence of water molecules.
Litmus paper changes colour only when H₃O⁺ ions are present in solution; dry HCl remains molecular (HCl) and cannot act as an acid without water to donate protons to.
