green chlorophyll is the most common type of pigment, but there are also carotenoids (yellow, orange) and anthocyanins (red). chlorophyll, which is essential for photosynthesis, usually hides the other pigments, except when autumn comes along and it begins to break down. this is why leaves turn different colors in the fall. do this project to see the hidden colors in a green leaf and predict what color it will be in the fall! (adult supervision recommended.) after about 30-90 minutes you should be able to see the “green” color break up into several different colors as the different pigments begin to separate. join our list for the latest on products, promotions, and experiments and receive free shipping on your first $50+ order. my science perks is free! just place your order while logged in to your home science tools account and you’ll automatically earn up to 6% back when your order ships! learn more >>
the leaves of most plants are green because of a special pigment called chlorophyll which is contained in the leaf cells. in this lab, we will attempt to separate these pigments. record in your data chart and include a sample calculation. leaf chromatography paper reveals the colors hidden by the green of summer. leaves contain different pigments, which give them their color. green chlorophyll is the most common type of pigment, but there are also carotenoids (yellow, orange) and anthocyanins (red). procedure: (what will the teacher/students do?) chromatography with leaves. – use a piece of masking tape to label a beaker with your name and class period., leaf chromatography lab report, leaf chromatography lab report, plant pigment chromatography lab answer key, leaf chromatography activity, leaf chromatography preschool

chromatography allows a sample, the solute, to be separated out into the samples different pigments and colors through the use of a solvent and capillary action. however, for chromatography to occur, the correct solvent must be present, a mixture must be able to be separated into differing pigments and finally the correct type of paper must be used to allow capillary action to occur. solvent helps separate the individual pigments in a mixture and the distance the solvent travels also helps to find the rf value. rf is a characteristic that is specific to a certain substance and is calculated by dunknown divided by dsolvent, which stands for distance solute traveled divided by distance solvent traveled. because rf values are consistent across consistent conditions, the value can be used to identify a substance by all scientists.
the chromatography paper was cut and set up and the solute was added to the beaker. the tip of the chromatography paper was then put into the solvent and the experiment sat for 10-15 minutes. the chromatography paper indicated that the green leaf is composed of yellow, light green and green pigments, while the non-green leaf contains orange, yellow, light green and green pigments. this experiment gives insight into what pigments different colored leaves are composed of and how calculating the rf value can indicate what pigment it is. the initial data from chromatography can lead to many other experiments and connections made between photosynthesis and leaf pigmentation.
