The distribution coefficient of an organic compound A for benzene and ...
Suppose amount of A extracted with 100 mL of benzene = xg. The amount of A left in 100 mL water = 1–xg
The amount of A extracted with 100 mL of benzene is 0.909 gm.
The amount of A extracted with 100 mL of benzene is 0.909 gm.

The distribution coefficient of an organic compound A for benzene and ...
Explanation:
Distribution Coefficient:
Distribution coefficient is the ratio of the concentrations of a solute in two non-miscible phases at equilibrium. It is denoted by Kd. In this problem, the distribution coefficient of the organic compound A for benzene and water is given as 10.
Extraction:
Extraction is a process of separating a solute from one phase by transferring it to another non-miscible phase. In this problem, organic compound A is dissolved in water and is to be extracted with benzene.
Calculation:
Given, distribution coefficient (Kd) = 10 and 1.0 gm of A is dissolved in 100 mL of water.
Let x gm of A be extracted when 1.0 gm of A dissolved in 100 mL of water is equilibrated with 100 mL of benzene.
At equilibrium, the amount of A in water phase = (1.0 - x) gm
Amount of A in benzene phase = x gm
According to the distribution law,
Kd = (Concentration of A in benzene phase) / (Concentration of A in water phase)
10 = x / (1.0 - x)
10 (1.0 - x) = x
10 - 10x = x
11x = 10
x = 0.909 gm (approx)
Therefore, the amount of A extracted is 0.909 gm.
Answer:
The correct answer is between 0.8 and 1.1 gm. The calculated value of 0.909 gm falls within this range.

Distribution coefficient is the ratio of the concentrations of a solute in two non-miscible phases at equilibrium. It is denoted by Kd. In this problem, the distribution coefficient of the organic compound A for benzene and water is given as 10.
Extraction:
Extraction is a process of separating a solute from one phase by transferring it to another non-miscible phase. In this problem, organic compound A is dissolved in water and is to be extracted with benzene.
Calculation:
Given, distribution coefficient (Kd) = 10 and 1.0 gm of A is dissolved in 100 mL of water.
Let x gm of A be extracted when 1.0 gm of A dissolved in 100 mL of water is equilibrated with 100 mL of benzene.
At equilibrium, the amount of A in water phase = (1.0 - x) gm
Amount of A in benzene phase = x gm
According to the distribution law,
Kd = (Concentration of A in benzene phase) / (Concentration of A in water phase)
10 = x / (1.0 - x)
10 (1.0 - x) = x
10 - 10x = x
11x = 10
x = 0.909 gm (approx)
Therefore, the amount of A extracted is 0.909 gm.
Answer:
The correct answer is between 0.8 and 1.1 gm. The calculated value of 0.909 gm falls within this range.
