Is chlorophyll soluble in water? This product is freely soluble in ether, ethanol, acetone, chloroform, carbon disulfide, and benzene. 5,6 It is sparingly soluble in cold methanol, practically insoluble in petroleum ether, and isnot soluble in water. ...
Biological pigments are the water-insoluble compounds that are responsible for color formation. Both plants and animals have various pigments. Biological pigments are also called biochromes. Apart from color formation, sometimes pigments also provide nutrition for that organism. Based on their sources pi...
Why is potassium permanganate colored? Why does the carotene elute from the column before the chlorophylls? Explain why pickles are stored in a brine (salt) solution. What would the pickles look like if they were stored in the water? Explain why the cation samples are repea...
Precipitates are the solid insoluble products produced in certain reactions which are taking place in a solution. Such reactions are generally termed precipitation reactions. Sodium chloride is an example of a precipitate. Answer and Explanation:1 ...
The separating funnel generally depicts the combination of two insoluble liquids (polarity difference: one is polar and other is non-polar). One is usually organic solvent and other is aqueous phase of water.Answer and Explanation: In the separating funnel, there are ...
It is suspected that a water-insoluble solid unknown is an amine. Which of the following would be useful in confirming the suspicion? (a) 6 M HCl solution (b) 3 M NaOH solution (c) Red litmus paper In part 4 of this experiment, you are asked to pr...
However, in these soils, Fe usually forms insoluble ferric compounds at neutral pH values, thus rendering it unavailable to plants. Therefore, Fe-enriched fertilizers could optimize the Fe supply of plants. Different studies have shown that Fe NFs increased germination and improved growth of ...
At this point, however, their precipitation into insoluble aggregates has to be prevented. If—primarily due to the release of vacuolar contents—the pH in the homogenate drops close to the viral pI (as an example, pI of 3.3 for TMV [245,246]), the virus particles might be lost due ...
