WebJan 23, 2024 · Synthesis. Modern industrial scale production involves the electrochemical oxidation of iodic acid, on a PbO2anode, with the following standard electrode potential: H 5 IO 6 + H + + 2 e − → IO −3 + 3 H 2 O E° = 1.6 V. Orthoperiodic acid can be dehydrated to give metaperiodic acid by heating to 100 °C. HIO 4 + 2 H 2 O ⇌ H 5 IO 6.
Periodic acid–Schiff (PAS) is a staining method used to detect polysaccharides such as glycogen, and mucosubstances such as glycoproteins, glycolipids and mucins in tissues.
