Chromic acid can only exist in aqueous solution, if it is precipitated from the aqueous solution, it will immediately decompose into chromic anhydride and water. Chromic acid has strong oxidability.
Chromic acid is most commonly used as cleaning liquid in the laboratory, both acidic and oxidizing, can remove the fouling and insoluble material of the inner wall and the outer wall of the experimental instrument. Usually the solution is obtained by adding potassium dichromate to concentrated sulfuric acid, but hexavalent chromium is harmful to the environment, and strong acidic conditions can sometimes damage instruments, so the use of chromate washes has been reduced.
