What are the types of chemical separation methods?
Examples are:- Adsorption- Chromatography- Decantation- Solvent extraction- Distillation- Crystallization- Electrophoresis- Filtration- Precipitation- Ion exchanging
How do you extract alkaloids from plants?
Alkaloids can be extracted from plants using various techniques such as solvent extraction, acid-base extraction, and chromatography. The process typically involves macerating the plant material, mixing it with a solvent (such as ethanol or methanol), filtering the mixture, and then evaporating the solvent to obtain the alkaloid extract. Purification may be needed using additional techniques such as column chromatography or crystallization.
How do you extract microbial pigments?
hot water extraction , aqueous extraction, solvent extraction
What is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
Why the descending method of chromatography is faster than the other method?
Descending chromatography is faster because gravity aids in pulling the solvent down through the stationary phase, allowing for quicker elution of compounds. In this method, the analytes travel with the solvent flow, resulting in faster separation compared to ascending chromatography where the solvent has to move against gravity.
How is extraction related to chromatography?
Both are techniques of analytical chemistry and use a solvent.
What is descending paper chromatography?
ascending chromatography is a type of chromatography in which chromatic substance is in mobile phase and moving from bottom to top. similarly in descending chromatography mobile phase moving from top to bottom.
What are the types of chemical separation methods?
Examples are:- Adsorption- Chromatography- Decantation- Solvent extraction- Distillation- Crystallization- Electrophoresis- Filtration- Precipitation- Ion exchanging
Differences between extraction and chromatography?
both the terms can be alternatively used but chromatography is seperation of mixture i.e. all the components in the mixture are seperated but in the extraction only the desired one is seperated
What are the two types of paper chromatogaphy?
The two types of paper chromatography are ascending chromatography, where the solvent moves up the paper, and descending chromatography, where the solvent moves down the paper.

Why does carotene travel farthest in chromatography of leaf pigments?
Carotene travels the farthest in chromatography of leaf pigments because it is the least soluble in the chromatography solvent. This means it interacts less with the solvent and more with the chromatography paper, allowing it to move further up the paper before the solvent front stops it.

What are the factors that affect leaf chromatography?
Factors that affect leaf chromatography include the polarity of the solvent used, the size and shape of the molecules being separated, the pH of the solvent, and the temperature at which the chromatography is performed. These factors can impact the rate at which the molecules move through the chromatography medium and the resolution of the separation.
