The yellow color in the test tube during an electrolysis water experiment is typically due to the presence of bromine or iodine. These elements can be released during the electrolysis process when the electrodes are made of certain materials that react with the electrolyte solution, such as potassium bromide or potassium iodide.
A test to confirm the presence of sodium gas in electrolysis is to introduce a dampened indicator paper near the electrolysis setup. Sodium gas will react with the indicator paper, turning it yellow due to the formation of sodium hydroxide. This indicates the presence of sodium gas in the electrolysis process.
You can test the gas collected in electrolysis of water by performing the pop test. Collect the gas in a test tube, turn it upside down, and place a lit match at the opening of the tube. If the gas is hydrogen, it will make a "pop" sound when ignited. Another method is to test the gas with a lighted splint; if it reignites with a pop sound, it is likely hydrogen gas.
The dependent variable in this experiment would be the time it takes for the sugar to completely dissolve in hot water.
A test tube experiment is commonly referred to as an "in vitro" experiment. This means that the experiment is conducted outside a living organism or natural setting, typically in a controlled laboratory environment using test tubes or other lab equipment.
A experiment done in a test tube is commonly referred to as an "in vitro" experiment. This type of experiment allows for controlled conditions within the test tube to study biological processes or reactions outside of a living organism.

You can test the evolved gases in electrolysis of water by collecting the gases separately in test tubes placed over the anode and cathode. The gas collected at the anode is likely oxygen, while the gas collected at the cathode is likely hydrogen. You can confirm their identities by performing simple tests such as the re-ignition test for oxygen and the "pop" test for hydrogen.

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.
The experiment is what you test and how you test it. Your entire project is based on the experiment.
The dependent variable in this experiment would be the time it takes for the sugar to completely dissolve in hot water.
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)
The test charge is positive in the experiment.
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.
just about any science experiment can test a hypotheses
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.
by putting a little drop of water on some salt under a telescope ;-)
