Chromium trioxide

Chromium trioxide (CAS NO.10043-01-3) is highly toxic, corrosive and carcinogenic. It is the main example of the environmental hazard known as "hexavalent chromium". The related chromium (III) derivatives are not particularly dangerous, thus reductants are used to destroy chromium(VI) samples. This monograph for Chromium Trioxide provides, in addition to common physical constants, a general description including typical appearance, applications, change in state (approximate), and aqueous solubility. The monograph also details the following specifications and corresponding tests for verifying that a substance meets ACS Reagent Grade specifications including: Assay, Insoluble Matter B. whereas chromium trioxide was included in Annex XIV to the REACH Regulation in 2013 (6) due to that classification, the high volumes currently in use, the high number of sites where it is used in the Union and the risk of significant exposure to workers (7), with a sunset date of 21 September 2017; Chromium trioxide, chromic acid. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).

Chromium trioxide was found to be toxic by the dermal route, compared to the other compounds in this group which were found to be harmful. The difference in dermal toxicity is attributable to more severe local corrosive effects caused by chromium trioxide.

Chromium trioxide consists of chains of tetrahedrally coordinated chromium atoms that share vertices. Each chromium atom therefore has "half share of two oxygen atoms" and two oxygen atoms that are not shared, giving an overall stoichiometry of 1:3. Chromium trioxide decomposes above 197°C liberating oxygen eventually giving Cr 2 O 3.
