Test for Hydrogen & Carbon Dioxide Flashcards

All 4 cards in this deck

Describe the chemical test for hydrogen and its positive result.

Apply a lighted splint to the gas; a squeaky pop is heard.

Describe the chemical test for carbon dioxide and its positive result.

Bubble the gas through limewater; the limewater turns cloudy (milky).

True or false? A glowing splint that relights shows a gas is hydrogen.

False. That is the test for oxygen; hydrogen gives a squeaky pop with a lighted splint.

A gas from a reaction does not turn limewater cloudy. What does this tell you?

The gas is not carbon dioxide.
