Hydrogen chloride gas turns the blue litmus paper:
1 Green
2 Red
3 Black
4 No change in colour
Explanation:
No change in colour The colour of blue litmus paper changes only in the presence of ions like hydrogen (H\(^{1}\)) or hydronium (H\(_{2}\)O\(^{1}\)) ions. HCl can produce these ions only in an aqueous solution. Hence dry HCl gas does not change the colour of dry litmus paper.
