Question

A form of machining that relies on this process can be used to complement EDM by deburring the material without encountering tool wear. A form of this process can be sped up with platinum and iridium-based catalysts that impact its HER and OER phases, respectively. Excessive fluorination is a major risk of using this (-5[1])process to create (-5[1])fluorine-carbon bonds in the Simons process. Antiquated forms (10[1])of this process used to manipulate alkali metal compounds include the conversion of sodium chloride to sodium hydroxide via the Castner–Kellner (10[3])process (10[2])and (10[1])Humphry (10[1])Davy’s (10[2])isolation of (10[1])potassium. (10[2])Faraday’s (10[1])laws (10[1])describing (10[1])this process (10[1])state that the mass deposited at an (10[1])electrode is proportional to the applied charge. For 10 points, (10[1]-5[1])name this (10[1])process exemplified by the splitting of water (10[1])into oxygen (10[1])and hydrogen by an applied current. ■END■ (10[2])

ANSWER: electrolysis [accept water splitting until “water” is read; prompt on electrochemical reactions or electrochemistry; prompt on electrochemical machining; prompt on electricity]
