The science of the interaction or interconversion of electric and chemical phenomena.
The science that deals with the use of electrical energy to bring about a chemical reaction or with the generation of electrical energy by means of chemical action.
The scientific study of the electrical aspects of chemical reactions, especially the changes they bring about in the arrangement and energy of electrons. Electrochemistry is vital to the study of electrolysis, power generation by electric cells, and the transmission of electrical signals by neurons.
