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
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
chromic acid solutions for finishing surfaces of metals, plastics and
ceramics can now be used in a closed-loop process wherein the chromic
acid solutions are continuously restored, purified and maintained at
desired process conditions.
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.
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 (also known as a
sulfochromic mixture) 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.
organic chemistry, dilute solutions of hexavalent chromium can be used
to oxidize primary or secondary alcohols to the corresponding aldehydes
Because of the oxidation is signaled by a color change from orange to a
blue-green, chromic acid is used as a qualitative analytical test for
the presence of primary or secondary alcohols.
Chromated copper arsenate, the principal wood preservative manufactured
from chromic acid, is providing virtually all the driving force for the
chromic acid market.
the next four years, U.S. chromic acid consumption is anticipated to
grow modestly, at 2.3 percent annually.
