Law of dilution

Wilhelm Ostwald’s dilution law is a relationship between the dissociation constant and the degree of dissociation of a weak electrolyte (acids, bases).

$$\mathsf{K_p = \frac{c(K^+) \cdot c(A^-)}{c(KA)} = \frac{\alpha^2}{1-\alpha} \cdot c_0}$$

Concerning conductivity, this results in the following relation:

$$\frac{\Lambda_c^2}{(\Lambda_0 - \Lambda_c)\Lambda_0}\cdot c = K_c$$
