Sustainable hydrogen electrolysis - without precious metals
Web3. nov 2012 · For any electrochemcial reaction, electrons are transfer from the oxidant to the reductant. By definition, any flow of charge per unit time period is an electric current. However, in the case of electrolysis, the electron transfer is not spontaneous. An external energy source is required for the reaction to take place. Webelectrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). The process is carried out in an electrolytic cell, an apparatus consisting of positive and negative electrodes held apart and dipped into a … WebElectrolysis is the only proven method of permanent hair removal when performed by a qualified professional.
