शुष्क हाइड्रोक्लोरिक गैस शुष्क लिटमस पत्र के रंग को क्यों नहीं बदलती है?
Option A
Option B
Option C
Option D
Solution
Colour of the litmus paper is changed by the hydrogen ions. Dry $HCl$ gas does not contain $H ^{+}$ ions. It is only in the aqueous solution that an acid dissociates to give ions.
since in this case, neither $HCl$ is in the aqueous form nor the litmus paper is wet, therefore, the colour of the litmus paper does not change.
