Chemistry tests gases and water.

?
What's the test for chlorine?
Hold damp litmus paper over chlorine and it will bleach it white,it will turn red for a moment though as chlorine is acidic.
1 of 22
What's the test for oxygen?
The test for oxygen is holding a glowing splint in a tube of oxygen and the splint will relight.
2 of 22
Wats the test for carbon dioxide?
Carbon dioxide will turn limewater cloudy,bubble the gas through lime water and watch it go cloudy.
3 of 22
What's the test for hydrogen?
Hydrogen when put near a lighted splint will make a squeaky pop.
4 of 22
Why does the hydrogen test make this noise?
The noise comes from hydrogen burning with the oxygen in the air to form H2O.
5 of 22
Wats the test for ammonia?
Ammonia turns damp red litmus paper blue,it also has a very strong odour.
6 of 22
What substance can be used to test water?
Copper(II) sulfate can be used to test water.
7 of 22
What happens when copper(II) sulfate is bound to water?
The copper(II) sulfate and water form blue crystals.
8 of 22
What happens if you heat the blue hydrated copper (II) sulfate crystals?
If you heat the hydrated copper(II) sulfate crystals it drives the water off.
9 of 22
By doing this process what does it leave?
The heating process leaves a white anhydrous copper(II) sulfate powder,which doesn't have any water bound to it.
10 of 22
What does anhydrous mean?
Anhydrous means without water.
11 of 22
What does hydrated mean?
Hydrated means with water.
12 of 22
What happens if you add water to the white anhydrous copper(II) sulfate powder?
The blue crystals will form again.
13 of 22
What do you need to test for water?
You need anhydrous copper (II) sulfate,if you add your substance to the white powder and it turns blue the substance is water.
14 of 22
What will this test not tell you?
This test will not tell you if the water is pure.
15 of 22
What does pure mean?
Pure means that the sample is made up of only one substance.
16 of 22
How does pureness affect the properties of the sample?
If the sample is pure it will stick to its defined physical properties such as boiling and freezing point.
17 of 22
What are the properties of pure water?
Pure water will always boil at 100 degrees and freeze at 0 degrees.
18 of 22
Which two tests do you need litmus paper for?
Chlorine need damp litmus paper,ammonia needs red litmus paper.
19 of 22
Which two tests need splints?
Test for hydrogen and oxygen.
20 of 22
Which test needs limewater?
The test for carbon dioxide.
21 of 22
Which test needs anhydrous copper(II) sulfate ?
The test for water.
