Water is used in an experiment because (for example) you need to separate a mixture, it can be evaporated. Basically, water is used because it is easier to work with since it can be in all three states (solid, liquid, gas). :)

What chemical do you use to identify carbon dioxide?
lime water is the name of the experiment...
Design an experiment that separates blue-green chemical from water?
You could boil the solution, leaving you with the blue-green chemical.
What is used as a medium for a chemical reaction?
Generally water is used as a medium for chemical reactions.
What is the need of ice cold water in chemical kinetics experiment?
to maintain the reaction so that we calculate the rate of reaction at that particular time.
Why water tested for each chemical?
It is the control group of the experiment. It provides a normal standard which the results of the experimental groups can be compared against.
Why distilled water use in chemical experiment?
distilled water is used in chemical experiments because you already have a control group (whatever type of water you used) and you need other groups that dont have the same water in them to compare the control group to!
What chemical do you use to identify carbon dioxide?
lime water is the name of the experiment...
Why is it important to let water to become still before an experiment?
If water is not still before an experiment then if the experiment involves measuring water then the measurement would not be accurate. Also if there is something in the water you might spill it out and spoil your experiment.
Does the temperature of the water effect a science experiment?
Yes. How much it affects the experiment depends on exactly what the experiment is and how much the temperature has changed, but any change in temperature affects water's physical and chemical properties.
Design an experiment that separates blue-green chemical from water?
You could boil the solution, leaving you with the blue-green chemical.
Can salt water and fresh water be used in a experiment?
if the salt or other impurities in 'fresh water' will not interfere with the experiment, yes.
Why must such as plants given water only be used in the fertilizer experiment?
Why must controls (such as plants given water only) be used in the fertilizer experiment
What is the chemical experiment used to find out if poison is poisonous?
Giving some to whatever you're trying to poison and seeing if it dies. It's more a biological experiment than a chemical one.
What experiment would tell you if water takes stuff with it when it evaporates?
I suppose that the chemical analysys of the condensed water can offer information.
What are the variables used in the experiment on germination?
water and light
Why salt solution is used in osmosis experiment?
Salt solutions are used in osmosis experiment to show that water will move to the side that has more salt. "Water follows salt."
How could the procedures used in this experiment be altered to measure bacteriostatic effects?
A bacteriostatic test chemical could be used.
