i measured 15mL of Ethyl Alcohol in a graduating cylinderThen, we marked the line of the chromatography paper with a brown marker Then, we transferred the Ethyl alcohol into to beaker and quickly covered the top of the beaker with the aluminum foilwe shaped the chromatography paper into a cylinder using a masking tapeOnce 2 minutes were over, we quickly lifted the aluminum foil, placed the chromatography paper inside the beaker, then placed the aluminum foil over the beaker again.we waited to see what was the result of the experimentThe results after the experiment we performed was that the Brown ink we marked on the Chromatography paper raised up the paper and spread into different kinds of colorsThe colors we saw when we took out the Chromatography paper were the colors Orange and Purple.my question is.why and how did those results happen??
Drink plenty of water, and just do more exercise than your calorie intakeRunning and Swimming is how I stay fit, because you can take them at your own pace Also make little changes in your diet, like switching to skimmed milk, light mayo, sweetners in tea and on cereals etcIt all adds up.
When the drwanted to put me on a diabetic diet, i figured why not eat rasta so i went back to ital eating .

You'll be glad to know it's not necessarily as hard as people make outI should know, since starting a regime about 7 weeks ago I've lost 23lbs and still goingI don't know if this is the right way of going about things but it's worked for meEat 6 or 7 times a day - to keep the metabloism going continuosly - small meals only!! Cut out fat as much as possible - or at least go to reduced fat everythingTake up sports - As well as going to the gym , I now play squash and football (soccer) Work out - I do about 60 mins of CV 4 times a week and weight training 2 times a weekCut out the booze - I found this the hardest of allI used to have a beer or three virtually every night - now I just drink on Saturdays and I don't drink beer any more - btw Vodka and soda is one of the cleanest drinks out there, it's nice with some fresh squeezed limeAnd that's it - no magical formula, just a bit of discipline reallyGood luck
This is called thin layer chromatographyYou know that the brown ink inside the marker is made up of many different dyesEach dye has its own color, and all colors add up, resulting the brown color you seeThe point is that some dyes have great affinity for paper (stationary phase), while some for solvent - ethyl alcohol, in this case (moving phase)Those which prefer the solvent will be dragged along, for the solvent diffuses through the paper due to capillarityThat's why you see spots of different colors spread all through the paperThe dyes which prefer the paper will attempt to stay still though.
