Explain Ostwald’s dilution law.

Ostwald’s dilution law is a relationship proposed in 1888 by Wilhelm Ostwald. Ostwald’s dilution law describes the dissociation constant of the weak electrolyte with the degree of dissociation (α) and the concentration of the weak electrolyte. Ostwald’s dilution law states that only at infinite dilution the weak electrolyte undergoes complete ionization.
