· The soluble pigment carotene dissolved into the acetone the easiest, and thus moved the furthest from the origin. The less soluble chlorophyll b did not dissolve as easily into the solvent; it instead was absorbed more readily into the fibers of the paper. Chlorophyll a moved further than chlorophyll b.

اقرأ أكثر· chlorophyll is excited from a lower energy state to a higher energy state. In this higher energy state, the electron is more readily transferred to another molecule. This starts a chain of electron-transfer steps, which ends with an electron transferred to carbon dioxide. Meanwhile, the chlorophyll which gave

Therefore, I concluded that the carotenoids are less polar than the chlorophylls and is more soluble than chlorophylls. THEN, and this is what makes no sense to me, we mixed a solution of ethanol and pigment with petroleum ether, shook it, and two ...
اقرأ أكثر· Chlorophyll is a magnesium-porphyrin compound that consists of a ring porphyrin (head) and a long hydrocarbon phytol (tail), both of which are bonded together by an ester bond . Chlorophyll is water-insoluble, but can be easily dissolved in organic solvents such as ethanol, acetone, ether, and chloroform .

اقرأ أكثر· Chlorophyll specifically, is only able to form complexes with other molecules to stay in solution at biological pH (7.4). Its natural environment is at a pH of around 4 not 7.4. At this pH it has a net charge of - 2 so that it can form a chemo-gradient for electron transport during photosynthesis. So since pH =-log [OH - / H +] when at pH 4 the ...
اقرأ أكثر· Is chlorophyll soluble in organic solvents? Chlorophyll is water-insoluble, but can be easily dissolved in organic solvents such as ethanol, acetone, ether, and chloroform [5]. What exactly is chlorophyll? Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

اقرأ أكثر· Acetone is a polar molecule, which gives it a strong intermolecular attraction to water, which is very polar. As a result, acetone is fully soluble in water.
اقرأ أكثر· Is chlorophyll a or b more soluble in acetone? Chlorophyll will be more soluble in all solvents above acetone and less soluble in the solvents below acetone. What does acetone do to chlorophyll? Acetone breaks down chlorophyll's lipid bonds to a plant's thylakoid structure and suspends the pigment in solution. Acetone is the standard ...

اقرأ أكثر· The unequal solubility causes the various color molecules to leave solution at different places as the solvent continues to move up the paper. The more soluble a molecule is, the higher it will migrate up the paper. If a chemical is very non-polar it will not dissolve at all in a very polar solvent.

اقرأ أكثرYes. Some organic compounds are soluble only in organic solvents. They do not dissolve in water. If they do not dissolve in water, those organic compounds are non-polar compounds.
