Abstract
The scanning-laser-beam chemical imaging sensor was applied for the observation of electrogenerated pH distribution on a mesoscopic scale. Electrolysis was carried out in potassium chloride solution and the resulting pH distribution was imaged with a 0.2 mm spatial resolution. As a result, the generation of the pH distribution and its expansion to the bulk region were clearly imaged. By examining the pH image, it was also possible to obtain the pH values in the pH-distributed regions separately from those in the bulk region.Keywords
