Question

Three joined upright cylinders perform this technique in a device invented by Hofmann. When run in reverse, regenerative fuel cells act as devices that perform this technique. Chlorine bubbles are (20[1])produced as a byproduct (20[1])of this technique (20[1])in (20[1])the Castner–Kellner (20[1])process. (20[6]0[1])This technique is performed on the output of the Bayer process in molten (*) cryolite ("CRY-oh-light") in the major industrial process to produce aluminum. Two laws named for Michael Faraday govern this technique and explain the mass deposited when plating metals. Performing this technique on water at an electrode produces hydrogen and oxygen gas. For 10 points, name this technique that splits (10[1])molecules using an electrical current. ■END■

ANSWER: electrolysis [accept electrolyzers; accept electrolysis of water; prompt on electrochemical reaction; prompt on water splitting until "water" is read]
