Abstract : The theory of stepwise dissociation of an electrolyte is set forth quantitatively using linearized equations to obtain solutions for relaxation times and maximum values of ultrasonic absorption per wavelength in terms of normal coordinates. Application of the theory to experimental results of sound absorption of 2-2 electrolytes is discussed and it is shown how to obtain numerical results for reaction rate constants and equilibrium constants. Comparison of results for alkaline earth metals and the first group of transition metals leads to some conclusions about formation of metal complexes. The mechanism consists of a gradual substitution of the solvent molecules in the different coordination shells of the metal ions, involving various effects such as ion-dipole interaction, dipole-dipole interaction, field stabilization of the ligands and stereospecific effects.
