Question

Ostwald�s dilution law is applicable to only

• A. strong electrolytes
• B. solute
• C. weak electrolytes
• D. solvent.

Answer 1

Answer: (C)

weak electrolytes

Answer 2

According to Ostwald's dilution law, the degree of dissociation of a weak electrolyte is proportional to the square root of dilution. $\alpha=\sqrt{\frac{K}{C}}$ $\alpha=$ degree of dissociation, $C =$ concentration $K =$ Equilibrium constant (dissociation)
