单词	Ostwald's dilution law
释义	Ostwald's dilution law An expression for the degree of dissociation of a weak electrolyte. For example, if a weak acid dissociates in water HA ? H⁺ + A^- dissociation constant K_a is given by K_a = α²n/(1 - α)V where α is the degree of dissociation, n the initial amount of substance (before dissociation), and V the volume. If α is small compared with 1, then α² = KV/n ; i.e. the degree of dissociation is proportional to the square root of the dilution. The law was first put forward by F. W. Ostwald to account for electrical conductivities of electrolyte solutions
