Schiff's Reagent

Mix 0.5 gm of Pararosaniline (C.I.#42500) into 15 ml of 1N Hydrochloric Acid. Mix 0.5 gm of Potassium metabisulfite into 85 ml of Distilled water. Add the second solution to the first and store for 24 hours in a dark place. Bleach the resulting solution with 200 mg of bone charcoal and filter. Store the colorless solution at 4C.
