Chromic Acid (Dichromic Acid, Chromium Trioxide Anhydrous)

Chromic Acid liquid solutions are an appropriate and cost-effective method of shipping bulk quantities. Liquids are convenient because the need for manual handling (crystal dissolving) is not required. Liquid chromic acid chemicals therefore, offer a cleaner, safer and healthier working environment and can lower costs, due to reduced housekeeping and maintenance requirements.

AD Productions is capable of producting custom chromic acid solutions tailored to specific customer demands.

Product information Chromium Trioxide

Chromium trioxide (dichromic acid, chromic acid) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, although in the general market place, the names are often used interchangeably. It is frequently used in the electroplating industry.
