How do you remove caffeine from a mixture?
Caffeine is removed in factories using super critical fluid extraction. That uses carbon dioxide under pressure (as a liquid) to pull the caffeine out, which can then be evaporated off. Caffeine can be extracted in an laboratory by adjusting to the right pH, followed by extraction with an organic solvent like hexane.
What is universal solvent?
A universal solvent doesn't exist; water is a good solvent for many materials.

What are the solute and solvent used in drinks?
Solvent is liquid such as water. Solute is the likes of caffeine, solutes dissolved. CO2 in soft drinks may be considered a dissolved gas until the drink is fully degassed
Is methanol a good solvent to use in paper chromatography?
Because methanol is a very polar solvent
Would ethanol be a good solvent for extracting caffeine from water?
No, water and ethanol are miscible in one another. This means they would not separate into two distinct layers when mixed. You would need a less polar solvent such as methylene chloride or ethyl acetate to achieve two layers and properly extract caffeine from water.
Is caffeine solute or solvent?
Caffeine would be a solute
Would water be a suitable solvent for extracting trimyristin from nutmeg?
no,trimyristin does not dissolve in water....ether will be the suitable solvent
What is the process for extracting essential oils called?
You think probable to solvent extraction.
What is the Rf value of caffeine in the solvent acetyl acetate?
Around .16
Is soxhlet extraction a good method in extracting and isolating nicotine from tobacco leaves?
Yes. Soxhlet extraction recycles the solvent so it passes through the sample in a lot of cycles so you can obtain a colored solvent solution in the end. This coloring is caused by the tobacco.
Why did the caffeine leave the water and move into the dichloromethane?
Dichloromethane is a water-immiscible solvent that works well, because caffeine is highly soluble in it
What are solutes and solvents?
A solute is the solid which dissolves in the liquid. And the solvent is the liquid. Ex: For tea, the water is the solvent and the caffeine is the solute. Therefore, when the solute and solvent are put together it becomes a solution.

Which method is more efficient several extractions with small amount of extracting solvent or one?
because it gives dilute solution
