Math Easy Solutions, here’s the corrected copy: “It is a typical electrolysis setup, where a direct current is applied between a palladium cathode and a platinum anode, with the electrodes immersed in heavy water (water in which the hydrogen is deuterium, an isotope of hydrogen containing one proton and one neutron) containing lithium deuteroxide as the electrolyte, typically inside a Dewar or vacuum flask used for calorimetry.” “An electrolyte is a substance that dissociates into ions in solution, allowing the solution to conduct electricity.” Sources: Wikipedia, UC Berkeley Understanding Science.
“The anode is where oxidation occurs, meaning a species loses electrons; in this case, the platinum anode mainly acts as an inert electrode, while oxygen gas is produced there from oxidation in the solution rather than from platinum itself ‘gaining oxygen.’” “At the cathode, deuterium is reduced and some may be released as deuterium gas, while some is absorbed into the palladium cathode.” Source: Wikipedia.
“The palladium absorbs deuterium, also called heavy hydrogen, into its metal lattice during electrolysis.” That last line is the clean fix because saying palladium “absorbs the electrons from the direct current” is the wrong chemistry.
