Acid-Base Extraction Flashcards
1
Q
Liquid-Liquid Extraction
A
a solution containing several components is mixed with a second immiscible solvent to extract one of the components into the second solvent
2
Q
Immiscible
A
does not mix to form a homogenous solution
3
Q
What are the principles of liquid-liquid extraction? (3)
A
1) The solvents used in liquid-liquid extraction are immiscible
2) Most uncharged organic compounds are insoluble in water
3) Charged organic compounds are more water-soluble
