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
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
Consider a mixture of water sand and oil.how many pahese are present?
You can separate them using chromatography.
What is the process of color separation called?
Chromatography. Take a piece of blotting paper, put a tiny drop of dye in the middle and then drip solvent (e.g. water, acetone, ethanol etc) onto the dye blot. The dye will spread out into separate coloured rings.
What is the purpose of using distilled water in pollen germination experiment?
pure water no impurities,,so that cannot disturb the result of the experiment

How do you separate the colours in biro ink?
Chromatography cannot be used because biro ink does not dissolve in water. I actually dont know how to separate the colors in Biro ink.. :( sorry, but look it up on google.com!
Describe an experiment used to find out whether there is any temperature change on mixing ethanol and water?
Measure equal amounts of water and ethanol in separate containers. Take temperature of both. Add ethanol to water and take temperature.
How do you collect ethanol if it is in a mixture with water?
Distillation. Ethanol can be easily collected from water using distillation up to 97% purity.
Can steam distillation of ethanol be done using a mixture of ethanol and water?
I dont think so because ethanol, containing an OH group is readily soluble in water.

How do you do chromatography?
I f you want to observe this theory in simple way ,you can observe it through using filter paper has ink on it and leave it in water ,after time when the water get evaporated you will observe that the ink was separated and this is a simple chromatography. And this is core concept for chromatography. Saleh Qahtani Lab Tech
How do you separate Ethanol and water?
Ethanol and water can be separated by fractional distillation. Fractional distillation separates liquid mixtures with different boiling points. Ethanol boils at a lower temperature than water. However, it forms a boiling azeotrope with water (azeotropes occur when solvent mixtures boil at a lower temperature than the component solvents). The azeotrope boils at 77.85 degrees, whereas pure ethanol boils at 78.4 degrees. The azeotrope is 96% ethanol and 4% water by volume. This is the maximum concentration of ethanol that can be achieved by simple distillation. Other methods of separating ethanol from water include using salts to make the water and ethanol phase-separate, using molecular sieves, using additives to change the azeotropic mixture, or distilling dry ethanol from wet ethanol that has been treated with a water-reactive metal, leaving behind the solid metal hydroxide.

Which entrainers can be used in ethanol water separation to obtain fuel grade ethanol?
Benzene or cyclohexane can be used in ethanol-water separation in order to allow distillation of ethanol past the azeotrope point (96.5% ethanol by volume). Of course the benzene (a known carcinogen) must be separated from the water before the water can be disposed. Fuel grade ethanol is often separated from water using molecular sieves. In this kind of separation water is entrained in "beads" which absorb water but reject ethanol. These are eventually regenerated for reuse.
What is the difference of absolute ethanol to the regular technical grade ethanol?
technical grade is bethween 96% and 98% ethanol and ethanol absolute means pure ethanol whithout water ('almost') 99.9% ethanol Absolute ethanol has no water whereas 96% ethanol has 4% water or 98% has 2% water. Thus, the reaction can occur with water.

Chromatography. Take a piece of blotting paper, put a tiny drop of dye in the middle and then drip solvent (e.g. water, acetone, ethanol etc) onto the dye blot. The dye will spread out into separate coloured rings.
