    Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase‚ which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds‚ causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention

    and that method of knowing is what we call “Candy Crhomatography”. Chromatography by definition according to Webster’s dictionary means “ a method for separating the constituents of a solution (gas or liquid) by exploiting the different bonding properties of different molecules”. In this case‚ the molecules being broken down are the different molecules that make up a certain color. Colors are basically made up of the primary (red‚ blue‚ yellow) and when you mix these colors together is when you get

    It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided.   When 4-aminophenol is t treated with

    Lab Design “Investigate the effect of a factor on the number of stomata of a leaf.” Research Question: How do differing leaf heights affect the number/density of stomata of a leaf? Hypothesis Stomata are pores‚ typically found under the leaf (lower epidermis)‚ that control the gas exchange of transpiration‚ where water vapor leaves the plants‚ and carbon dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts
