How will you test the gas collected in electrolysis of water?
pop test for hydrogen at -ve electrode glowing splint test for oxygen at +ve electrode
What test can be carried our to confirm the presence of sodium gas in electrolysis?
Electrochemistry is the test that can be carried to confirm the presence of sodium gas in electrolysis.
What is the dependent variable in an experiment to test how fast sugar dissolves in hot water?
The temperature of the water.
Why is the test tube with distilled water included in the laboratory activity?
the purpose of distilled water is so that chemicals in the water do not interfere with the experiment :)
How could a sample gas be collected at the positive electrode when using electrolysis for copper?
Place an inverted test tube over the elctrode

What is the dependent variable in an experiment to test how fast sugar dissolves in hot water?
The temperature of the water.
What experiment can you use to test if sugar is a covalent bond?
Sugar is not dissociated in water.
What is the experiment in a science fair project?
The experiment is what you test and how you test it. Your entire project is based on the experiment.
What is the role of water in the Benedict reagent?
It acts as a control for the experiment so that you can compare the result (of benedict's test in water) with the other test (using food with sugar)
Why is double the amount of gas collected in one of the test tube on electrolysis of water name the gas?
Water contains two parts hydrogen and one part oxygen (2 H and 1 O = H2O) Because of this, the amount of hydrogen and oxygen produced during electrolysis of water is in a 2:1 ratio. In electrolysis process, hydrogen goes to one test tube and oxygen goes to another. Because Water contains 2 part hydrogen, the amount of gas collected in one tube is double the amount collected in the other.
Does a experiment test a theory?
i dont no but i need the anwser Yes an experiment will test a theory. You perform an experiment to test the hypothesis. If the experiment can be repeated then the hypothesis becomes a theory. People perform experiments to test and retest theories.
What type of experiment can test a hypotheses?
just about any science experiment can test a hypotheses
What makes a test fair?
to ensure a fair test, the scientist carrying out the experiment must be fair skinned with fair hair. otherwise the test will not be fair, obviously. Another way to do a fair test is to talk around a fair, try out the rides and evaluate.
What experiment would be used to test for dissolving of salt in water?
by putting a little drop of water on some salt under a telescope ;-)
Can control in an experiment be changed?
no the control is that which is used to test your hypothesis. if mentos would blow up if you use caffeine and you used water, coke, and milk the water would be the control without it you cant do an experiment.
