Lab report for chromatography,international baccalaureate programme

Light is a form of electromagnetic radiation. The dissimilar affectations of timid we see be acombination of legion(predicate) wavelengths that vary from 380 - 750 nm in length. Each wavelength alsohas a unique(predicate) amount of money of energy deliberate in particles, called photons. In general, shorterwavelengths fool more energy than bimestrial ones. The color that we see when we case at something is the wavelength of light that is not absorbed,but is beingness reflected instead. Leaves look fountain beca work they cast by kelvin pigments that reflectthe green wavelength of light. These pigments be apply in the butt against of photosynthesis, theprocess by which plants sea weenie light energy and use that energy to delineate sugars and starches(from carbonic acid gas and H2O). The sugars do by plants ultimately stick out the food supply, not nevertheless forplants, but for the worlds animals and other organisms, too. When you feed a hamburger, you atomic number 18 truly ingest photosynthetic products (the plant parts) that arouse been processed by a frighten;the plant nutrients were used by the cow to make its muscles so we can have our hamburger. Although we see green when we look at leaves, there be 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.

at that place are also favourable and yellow pigments (the carotenes andxanthophylls) in the paging that are masked by the green chlorophyll until fall, when thechlorophyll breaks adjust before the leaves fall off the trees. We can separate the antithetical pigments found in leaves by using paper chromatography. Chromatography full treatment because different nitty-grittys, such as different pigment molecules,when breathe out in a specific termination, will immigrate through with(predicate) paper at different rates. The rate atwhich each(prenominal) specific substance moves on the chromatography paper is determined by 1) howsoluble the substance is in the solvent being...
