• Chromic acid generally refers to a collection of compounds generated by the acidification of solutions containing chromate and dichromate anions or the dissolving of chromium trioxide in sulfuric acid.
• Chromium trioxide is called chromic acid.
• Chromic acid ( chromium trioxide, CrO3) is an odorless red deliquescent solid.
• Chromic acid features chromium in an oxidation state of +6 (or VI), often referred to as hexavalent chromium.
• Chromium trioxide is produced commercially by the reaction of sodium dichromate with concentrated sulfuric acid or by electrolysis of sodium dichromate.
• The closed loop is maintained using an Electrodialytic Process for conversion of chromium+3 to chromic acid and the removal of metal cation impurities from the loop.
• Chromic acid plating solutions has predominantly been accomplished by either electrolytic or ion exchange methods.
• Most ion exchange systems for chrome purification are based on the Recoflo ion exchange process.
• Chromic acid is an intermediate in chromium plating, and is also used in ceramic glazes, and colored glass.
• Because a solution of chromic acid in sulfuric acid is a powerful oxidizing agent, it can be used to clean laboratory glassware.
• Chromic acid has also been widely used in the band instrument repair industry, due to its ability to "brighten" raw brass.
• Chromated copper arsenate, the principal wood preservative manufactured from chromic acid, is providing virtually all the driving force for the chromic acid market.
• Over the next four years, U.S. chromic acid consumption is anticipated to grow modestly, at 2.3 percent annually.
