What happens if the eluent is above the 1.5cm line in a chromatography experiment?
If the eluent is above the 1.5cm line in a chromatography experiment there will not be a proper distribution in a test tube to discover the sources of ink on a paper. A chromatography experiment tests for the sources of ink whether it be chemical or plant based.
An experiment was performed in lab that was supposed to produce aspirin. How could chromatography be used to tell if aspirin was actually the product of the reaction?
i would recommend using high performance liquid chromatography or the common thin layer chromatography using a spot of the sample and a spot of dissolved aspirin to compare the Rf-value or relative retention times of the 2 spots to determine if you have aspirin
What simple experiment can be used to determine if a liquid compound contains polar molecules?
Thin Layer Chromatography (TLC) procedure can be used
Why would ethanol work but not with water when using felt tip pens in an chromatography experiment?
Ethanol would work because it is alcohol-induced, therefore, it is stronger than water.
Why ethanol not suitable in Gas chromatography?
Its alcohol so it can purify the chemicals used in the experiment. Furthermore, it will travel up the filter paper better than water will. Ethanol is pure whereas water may have other things in it such as chlorine is in tap water

Why is fractional distillation an important experiment?
because it is important
How do you show a drink contain two different yellow substance by experiment?
I Think By Fractional Distillation

What lab equipment do you need for a desalination experiment?
You need a way to boil the water and allow the condensation to collect in a condensation coil that leads to a container holding the water
What would be the result if the spots were made to large in a thin layer chromatography experiment?
it would be difficult to read as they would merge
What is a flat bottomed flask used for in chemistry?
Some uses are:- experiment of chemical reactions- distillation- rotating evaporators
What is the problem with using a simple distillation apparatus a glass tube?
The problem with distillation is how to turn all of the hot vapour back into liquid. A simple distillation experiment using just a glass tube as a condenser, rather than a Liebig one, loses most of the steam.

What do scientists make to help them make an hypothesis or collect data during an experiment?
They make experimental condensation of the eutrofication. ! ;)
What is the function of acetone in chromatography experiment?
acetone used to absorb light in order to produce chemical energy in form of ATP
When human DNA is analysed using chromatography what are the results called?
I so want to say "genetic fingerprint" but I am crushed by the poor/overly brief wording of the question that perhaps I won't. Do we know what type of chromatography is being used? Do we know any more details of the experiment?
