CHROMIC ACID FLAKES

Product Description

~~Chromic Acid Flakes is also called Chromium Trioxide or Chromic Acid Anhydride.

This is available in the form of small flakes of dark red or chocolate coloured appearance, which are easy to dissolve in water. It is hygroscopic in nature and forms a saturated of *2.6% CrO3 at *5 degrees Centigrade. Though it is an acid, dilute solutions of it exert a protective action on metal surfaces like mild steel, zinc, aluminum, copper, brass etc. at room temperature, by the formation of a thin passivating film.

Applications

The largest use of Chromic Acid is in the Electroplating Industry. Electrodeposition of chromium bith as decorative and as hard chrome types are done with chromic acid only. Other uses are as dilute solutions for passivating or inhibition on metal surfaces, as an oxidising agent for organic chemicals and as a laboratory re-agent.
