Question

Distribution law was given by:

• A. Ostwald
• B. Nernst
• C. Henry
• D. Van't hoff

Answer 1

Answer: (B)

If a solute X distributes itself between non-miscible $A$ and $B$, at constant temperature and $X$ is the same molecular condition in both the solvents, then, this law is known as Nernst distribution law.

$\frac{\text{Concentration of}x\text{in}A}{\text{Concentration of}x\text{in}B}=k^{\prime }d$

Where; k'd is the distribution coefficient.
