Chromic acid include of acid substances, 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. Often the species are assigned the formulas H2CrO4 and H2Cr2O7.
The anhydride of these "chromic acids" is chromium trioxide, also
called chromium (VI) oxide; industrially, this compound is sometimes
sold as "chromic acid." Chromic acid forms are usually as chromic acid
flake or chromic acid powder. Chromic acid flake form usually as
technical practice and powder use for analytical purpose. Sunday, October 15, 2017
