Sample questions

1. Which of the following BEST describes the Nernst distribution law?

a.At constant temperature, a solute distributes itself between two miscible solvents in a constant ratio, regardless of its molecular state.

b.At constant temperature, a solute distributes itself between two immiscible solvents in a constant ratio, provided it remains in the same molecular state.

c.At constant volume, a solute distributes itself between two immiscible solvents in a ratio inversely proportional to their densities.

d.At constant pressure, a solute distributes itself between two miscible solvents in a variable ratio, depending on the volume of each solvent.

2. A solid X is added to a mixture of benzene and water. After equilibration, the concentration of X in benzene is 0.013 g/mL and in water is 0.0022 g/mL. What is the distribution coefficient (Kd) of X between benzene and water?

a.0.340

b.0.169

c.5.909

d.2.950

3. Which of the following is a PRIMARY application of the Nernst distribution law in pharmacy?

a.Understanding drug absorption and distribution between aqueous and lipid phases

b.Calculating the shelf life of a pharmaceutical solution

c.Predicting the rate of tablet disintegration

d.Determining the osmotic pressure of a solution

4. Which of the following is a condition for the valid application of the Nernst distribution law, rather than a limitation?

a.The presence of adducts or chemical changes in the solute

b.The use of dilute solutions at equilibrium

c.Temperature dependence of the distribution coefficient

d.Changes in the pH of the system

5. The term 'solubility' in a pharmaceutical context is BEST defined as:

a.The rate at which a solid drug particle dissolves in a biological fluid.

b.The ability of a drug to dissolve in a solvent to form a homogenous mixture at a specified temperature and pressure.

c.The total mass of a drug that can be suspended in a given volume of solvent.

d.The maximum concentration of a drug that can be achieved in a solid dosage form.
