A series of solvents with an increasing degree of polarity, generally used to explain solvent strength in liquid-solid or adsorption chromatography. A nonpolar solvent such as pentane would be at one end of the scale; dichloromethane would be an intermediate solvent; a strongly polar solvent, such as water, would be at the other end of the scale. Thus, when developing a method or running a gradient, an eluotropic series is useful for selecting solvents.

What is substance that have 0.803 Rf value?
The Rf value of a substance is a measure of its migration distance during chromatography. A substance with an Rf value of 0.803 would mean that it traveled 80.3% of the total distance from the origin to the solvent front during the chromatography process. The specific identity of the substance would depend on the experimental conditions and the properties of the compound.
Why is chromatography used in the police?
the police use chromatography to solve crimes, for example if they wanted to solve if a drug or a substance was illegal or legal they would use paper chromatograhy which would mean they would place the substance or a drug on paper dip it in a testing liquid which could be water for example and if the paper turns purple for example that liquid may be illegal or if that dot of the certain substance rises over 5cm for example it may be illegal so chromatography comes in very handy for the police and solving there crimes ! Hope this helped ;) xxx

What is the relation between mean median and mode?
In a symmetric distribution, the mean and the median are the same. Otherwise there is no relation. In symmetric distributions with only one mode, the mode will coincide with the mean and median, but otherwise there is no relation.
