When testing for Gases, where should the Experiment be done? | -This should be in a Fume Cupboard, so that Toxic Gases don't Spew out to the Classroom |
How can you test for Carbon Dioxide? | -Get a Solution of Limewater, and have the Gas bubble through it
-If the Limewater turns Cloudy, its Carbon Dioxide |
How can you test for Hydrogen? | -This is the unique 'Pop' Test.
-Using a Lighted Splint, put it in the Gas, and if it Pops, its Hydrogen |
Why does the Test for Hydrogen have a Pop? | -This noise comes from the Hydrogen burning with the Oxygen from the Air, to make Water |
How can you test for Oxygen? | -This can be done by using a Glowing Splint
-Put the Glowing Splint in the Gas, and if it gets Relit, its Oxygen |
How can you test for Chlorine? | -This can be done, by using a Damp Blue Litmus Paper
-Simply insert it in the Gas
-If it bleaches, its Chlorine
-If it goes Red for a moment, then its also Chlorine. This is because Chlorine is Acidic |
