The “Walker arrangement” is preferred while using this process to remove bismuth impurities from lead in the Betts process. Performing this process on heavy water near a palladium surface led Fleishmann and Pons to erroneously claim they had observed cold fusion. Using a PEM for this process has superseded the Castner-Kellner process. This process’s yield equals (*) I t M over F times v according to a set of two laws describing this process named for (10[1])Michael Faraday. Alumina is dissolved in a bath of molten cryolite before this process is applied to extract pure aluminum in the Hall–Héroult process. When applied to water, this process leads to hydrogen gas appearing at the cathode and oxygen at the anode. For 10 points, name this process of breaking apart molecules by applying an electric current. ■END■
