Description

General description

Sulfuric acid is a strong mineral acid. It participates as a medium in the anodic oxidation of aniline at a platinum electrode. Anodic oxidation has been reported to proceed via a free radical mechanism and octamer emeraldimine has been obtained as a major product.

Application

Sulfuric acid solution has been used as a solvent for the preparation of 1M xylenol orange and 2.5mM ammonium ferrous sulfate solution in a study.
