In the Bauer-Faulen stain, which oxidizing agent is used?

Explanation:
In this stain, the oxidative step is what makes the reaction detectable. Chromic acid acts as the oxidizing agent to convert certain carbohydrate residues in mucopolysaccharides and related substances into aldehyde groups. Those aldehyde sites then react with the dye system (often a Schiff-type reaction) to produce the color, highlighting the carbohydrate-rich components in the tissue. Other oxidizers listed are used in different stains or contexts and do not serve this specific role in the Bauer-Faulen method.
