Ostwald's Dilution Law explains the behavior of weak electrolytes in solution.

• Formula: $\alpha =\sqrt{\frac{K_a}{C}}$ (valid for low ionization).
• Here, $\alpha$ is the degree of dissociation and $C$ is molarity.
• The law states that the degree of dissociation is inversely proportional to the square root of the concentration.
• This means that as the solution is diluted (concentration decreases), the degree of dissociation increases, reaching $100\%$ at infinite dilution.
