how is this gas dentified
Answers
Answer:
Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.
Answer:
We've all been there; you have a bunch of unknown gases trapped in test tubes, and you need to figure out what you're dealing with. Okay, maybe we haven't all been there, but there are some nifty ways you can identify gases by using burning splits, limewater, or litmus paper. Most of the gases we'll focus on are colorless and odorless, so it's not possible to identify them by appearance.
In order to perform the tests, you'll need the following supplies:
Test tube of mysterious gas (with a stopper, so the gas doesn't escape)
Wooden splints
Matches
Goggles
Limewater (we'll go over the prep for this later)
Rubber tubing, glass rod, and a one-holed stopper
Litmus paper
