5.2.2 Electrogenerated Acids
In contrast to EGBs, the vicinity of an anode
becomes acidic during electrolysis. The acid
thus formed is called an electrogenerated acid
(EGA), which has unique reactivity compared to
conventional chemical acids. For instance,
electrolysis of a solution containing LiClO 4 and
a trace amount of water generates acid, HClO 4 ,
as shown in Figure 5.8 [30].
Figure 5.8 Principle of electrogenerated acid
EGA generated in this way is assumed to be
anhydrous HClO 4 , which is a stronger acid than
commercially available aq. HClO 4 . Such EGA
