Flashcards

Testing for Hydrogen Gas

Collect gas, light a splint, place in gas, listen for a squeaky pop sound, Confirm Hydrogen Gas if there is a squeaky pop.

Testing for Oxygen Gas

Collect gas, light a splint and blow it out, place glowing splint in gas, if splint relights, oxygen is present.

Testing for Carbon Dioxide Gas

Collect Gas, and observe for any specific reaction or visual changes. No mention of specific reactions are provided in the text, but this is a starting point.

What gas does acid produce when reacted with carbonates?

When acids react with carbonates, they produce carbon dioxide ($CO_2$) gas. This reaction is similar to acid rain interacting with marble.
