Alcohol is used only in the chromatographic separation of substances that do not dissolve in other common solvents but dissolve in alcohol.

Why do you use isopropyl alcohol for the chromatography experiment, and not water? In the case of gas-liquid-chromatography (glc) solubility of the volatile solute in the carrier liquid is useful as a means of collection of a trace compound.

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 ...

For this experiment, we use gas chromatography to study alcohols, which are very volatile. This means that we are easily able to vaporize it and study alcohols using this technique. The goal is to accurately determine the identities and amounts of the alcohols that comprise an unknown solution.

Chromatography is used in crime scene testing to analyze blood and urine samples for poisons, toxins, or alcohol levels. It is also used to test for doping or performance enhancing drugs in athletes. While the chromatography techniques used in these instances is more advanced than can be carried out in a school lab, we can utilize the technique of paper chromatography to separate the colored chemicals or substances in a mixture. How does it work?

For more advanced students, explain that the alcohol is a better solvent for chromatographic separation [dissolving the ink] than water due to polar and non-polar interactions.) Do you see any of the indicators of reaction?

If water works as the mobile phase as well being the stationary phase, there has to be some quite different mechanism at work - and that must be equally true for other polar solvents like the alcohols, for example. Partition only happens between solvents which don't mix with each other. Polar solvents like the small alcohols do mix with water.

The p -anisaldehyde and vanillin stains are general purpose, and work for many strong and weak nucleophiles (alcohols, amines), and for many aldehydes and ketones. They do not work on alkenes, aromatics, esters, or carboxylic acids. The TLC plates need to be mildly heated, and will develop a light pink to dark pink background.

Column chromatography is a common technique used to separate individual compounds from a mixture. You can use column chromatography on both a small or large scale to isolate and purify material for use on a later experiment. If you are new to column chromatography or just want a refresher, then read on for a quick description of the basic process.

You can use paper chromatography to see the different pigments that produce the colors in leaves.Most plants contain several pigment molecules, so experiment with many species of leaves to see the wide range of colors. This is a simple science project that takes about 2 hours.
