WebOstwald’s dilution law. Ostwald’s dilution law relates the dissociation constant of the weak acid (Ka ) with its degree of dissociation (α) and the concentration (c). Degree of dissociation (α) is the fraction of the total number of moles of a substance that dissociates at equilibrium. α= Number of moles dissociated / total number of moles. WebKa= a2C / (1-a) is known as the Ostwalds dilution law. For weak bases, Kb= a2C / (1-a) and a = rt (Kb/C) at a = small values. Kb = dissociation constant for weak base. This law fails for strong electrolytes. For strong electrolytes, a tends to 1.0 and therefore Ka increases tremendously. Prev Page.
