Answer: Ostwald’s dilution law states that “The degree of dissociation of a weak electrolyte is inversely proportional to the square root of molar concentration or directly proportional to the square root of volume holding one mole of the solute for a weak electrolyte.”
Its mathematical formula is Ka=a²C/(1-a).
Ostwald used the law of mass action in ionic equilibrium, which is analogous to chemical equilibrium because ions are in equilibrium. He devised an equation for the fluctuation of an electrolyte’s degree of ionisation with dilution, which is known as Ostwald’s dilution law.
