A method and apparatus for application of electrostatic charges to compounds to change the physical characteristics of the compounds. The compound is located within a container, that can be sealed or open, in proximity to an electrode so that there is capacitive coupling between the electrode and the compound. A high frequency, high voltage signal is applied to the electrode for a time sufficient to increase negative ions in the compound, thus changing its physical characteristics. The method can increase the pH and decreases oxidation-reduction potential. A grounded platform is provided for use with a non-conductive container, and the entire apparatus can be provided in a housing enclosure to permit safe application of electrical potential to the compound being treated.
