Conductivity of the distilled water and diluted electrolytes in the presence and absence of dissolved oxygen is studied. It is established, that the pure water containing oxygen has its own structure, capable to keep active forms of oxygen. Conductivity is realized as a result of movement of protons in molecular clusters of H2O, and conditions of change of this structure arise at an influence of an electromagnetic field and presence of particles of oxygen active forms possessing own magnetic moment. Presence of both positive, and negative values of an imaginary part of an impedance spectra specifies in equiprobable possibility of realization of a chain both capacitor, and inductive type. It is revealed, that a pulse transforma- tion of energy in the electrochemical system containing water, saturated with oxygen is possible in ranges of the frequencies having negative values of an impedance phase angle shift. In the absence of oxygen such a scheme is not realized.
