Description

Ammonium persulfate is used as a strong oxidizing agent in histological staining to produce an insoluble precipitate of silver sulfide on the tissue. It is also used for the manufacture of glycol ethers, which are solvents that are used in paints, varnishes, and lacquers. The reaction mechanism of ammonium persulfate is complex and involves three stages:
1) Ammonium persulfate reacts with water vapor to form hydrogen peroxide and ammonia gas.
2) Potassium dichromate reacts with hydrogen peroxide to form chromic acid and water.
3) The ammonium ion reacts with chromic acid to form a soluble salt (chromium(III) ammonium nitrate).
The reaction solution contains ammonium ions, which can be detected by electrochemical impedance spectroscopy (EIS).
