Question

Ostwald's dilution law is applicable on:

• A. strong electrolytes
• B. weak electrolytes
• C. both strong and weak electrolytes
• D. none of them

Answer 1

The correct option is B weak electrolytes

Ostwald's dilution law is applicable for weak electrolytes because strong electrolytes are $100$% ionized at all concentrations while ionization of weak electrolytes increases with increase in dilution. Dilution law is a relationship between the dissociation constant and the degree of dissociation of a weak electrolyte.
