Question

If a solute in water has a concentration of 0.12 mg/mL and has a concentration in ether of 0.60 mg/mL, what is the distribution coefficient, K, between ether and water

Answer 1

K = 5

Step-by-step explanation:

Distribution coefficient, K, is defined as the ratio between the concentration of a solute in two inmiscible solvents.

K = Concentration in solvent 1 / Concentration in solvent 2

Usually solvent 2 is water.

Replacing with the concentrations in the problem:

K = Concentration in ether / Concentration in water

K = 0.60mg/mL / 0.12mg/mL

K = 5
