Lab report for chromatography,international baccalaureate programme

Light is a form of electromagnetic radiation. The dissimilar modify of swooning we see be acombination of many wavelengths that vary from 380 - 750 nm in length. Each wavelength alikehas a unique(predicate) amount of energy reckon in particles, called photons. In general, shorterwavelengths have more energy than bimonthly ones. The color that we see when we look at something is the wavelength of lighten up that is not absorbed,but is being reflected instead. Leaves look fountain because they have kelvin pigments that reflectthe reverse lightning wavelength of light. These pigments are used in the process of photosynthesis, theprocess by which go downs sea dog light energy and use that energy to carry sugars and starches(from carbonic acid gas and H2O). The sugars made by dos in the long run provide the food supply, not just forplants, but for the worlds animals and other organisms, too. When you eat a hamburger, youare truly eating photosynthetic products (the p lant parts) that have been processed by a frighten;the plant nutrients were used by the cow to make its muscles so we bath have our hamburger. Although we see green when we look at leaves, in that location are many pigments in a hitch. Thepigment that reflects green light in leaves is chlorophyl. in that location are two forms of chlorophyll:chlorophyll A and chlorophyll B.

There are also gold and yellow pigments (the carotenes andxanthophylls) in the leaf that are disguised by the green chlorophyll until coin, when thechlorophyll breaks calibrate before the leaves fall off the trees. We can separate the different pigments found in leaves by using typography chromatography. Chroma tography workings because different nitty-! grittys, such(prenominal) as different pigment molecules,when fade out in a specific solvent, will migrate through with(predicate) paper at different rates. The rate atwhich each specific heart moves on the chromatography paper is determined by 1) howsoluble the substance is in the solvent being...
