Hello there, I did an extraction of caffeine organic lab experiment. Why is ethyl acetate used for extracting caffeine and not other solvents? I know that ethyl acetate, caffeine, and water are polar but why are two layers formed after mixing caffeine in water and ethyl acetate? I'm a little confused. I thought that polar mixes with polar and nonpolar mixes with nonpolar. Is caffeine not polar? Is ethyl acetate soluble in water? Please explain. Thank you very much! :)

    An experiment performed using solid to liquid extraction, liquid-liquid extraction, heating, and recrystallization to isolate caffeine, was not totally successful due to their being very little to no product of caffeine left when the time came to recrystallize the pure caffeine. During the experiment what could of caused there to be not enough caffeine to recrystallize it? ethyl acetate was used as the organic solvent hexane and acetone was used to recrystallize the crude caffeine, through mixture and boiling. Could...

    Explain why the most polar compound layer stays in the organic layer, while the less polar compounds go into the aqueous phase. (This is for a liquid-liquid extraction) The most polar compund is caffeine and the solvent is ethyl acetate. I know it has to do with the caffeine not being able to deprotonate but I’m still confused and would like more information on why is can’t deprotonate.

    I performed an experiment recently, and found potassium nitrate (KNO3) to be soluble in water but not hexane; and to have a red/green light color and insensity and a strong conductor (conductivity). But potassium nitrate I found is non-polar, I thought non-polar molecules didn't dissolve in water and are generally weak conductors? please explain how this is possible, thank you. NOTE: I know KNO3 is ionic, and most ionic bonds are polar; so, I'm confused as to how it is...
