Question 1

11.1b Define Extration

Answer 1

the use of 2 phases to extract a third substance from 1 of the two phases

Question 2

Kh

Answer 2

the equilibrium constant for partitioning (sự chia ra) of the type CH4(g) = CH4aq

Question 3

Kow

Answer 3

the equilibrium constant (or partition coefficient) for partitioning of a compound btw the two liquid phases of octanol and water

Question 4

Partitioning

Answer 4

equilibrium for a compound (ethanol) established as it moves across the surface between two phases (aqueous and gaseous phases in distillation)

Question 5

Phase

Answer 5

exists when it is surrounded by a surface
water can exist in 3 phases
oil + water are left to separate from each other, they hve surface btw them with 2 liquid phases

Question 6

Answer 6

the equilibrium constant for partitioning of the type:

Ethanol(l) Ethanol(g)
