is introduced? A small piece of zinc was added to HCl. To test the nature of the gas bubbles evolved, a burning splint was brought to the mouth of the test tube. The presence of hydrogen was shown by a flash or audible "pop." What Other Gases Are Like This?
 
Oxygen relights a glowing splint.

Carbon dioxide turns lime water milky.

Water vapour turns cobalt chloride paper pink.

They're the only ones I can remember.
