Question

Ostwald's dilution formula is applicable for which type of electrolyte?

• A. Strong Electrolyte
• B. Weak Electrolyte
• C. Both of the above
• D. None of these

Answer 1

The correct option is B Weak Electrolyte

Wilhelm Ostwalds dilution law is a relationship between the dissociation constant Kd and the degree of dissociation of a weak electrolyte.

The law holds good only for weak electrolytes and fails completely in the case of strong electrolytes as $\alpha$ is nearly equal to 1 for strong electrolytes.
