What are the tests of hydrogen and carbon dioxide?

In: Chemistry [Edit categories]

Answer:

If you put a burning splint overtop of a test tube full of hydrogen, it will pop. If you put a burning splint in a test tube with carbon dioxide, it will be extinguished. Also, if you bubble carbon dioxide through limewater (saturated calcium hydroxide solution). Carbon dioxide reacts to form calcium carbonate which turns the liquid cloudy.

Ca(OH)₂ _(aq) + CO₂ _(g) → CaCO₃ _(s) + H₂O _(l)
