Froehde Reagent

Froehde is one of the most widely used test to detect a wide rage of compounds. It is typically used as a secondary or tertiary test to validate results yielded by Marquis and Mandelin/Mecke (typical secondary tests). 


The Standardized method for producing the reagent is the addition of 100 ml of hot, concentrated (95–98%) sulfuric acid to 0.5 g of sodium molybdate or molybdic acid.
The Virginia University method uses 0.5 g ammonium molybdate per 100 ml H2SO4 (conc.)
