text: Wilhelm Ostwald’s dilution law is a relationship proposed in 1888 between the dissociation constant  and the degree of dissociation  of a weak electrolyte. The law takes the form
  Where the square brackets denote concentration, and  is the total concentration of electrolyte.
  Using , where  is the molar conductivity at concentration c and  is the limiting value of molar conductivity extrapolated to zero concentration or infinite dilution, this results in the following relation:
