What is the Prussian blue test?

Prussian blue is formed in the Prussian blue assay for total phenols. Samples and phenolic standards are given acidic ferric chloride and ferricyanide , which is reduced to ferrocyanide by the phenols. The ferric chloride and ferrocyanide react to form Prussian blue.
