Chromic acid H2CrO4 - PubChe

/Chromic acid:/ This important acid is known also as chromium trioxide. The technical grade is obtainable from primary producers in an anhydrous form as small dark red flakes containing 99% CrO3. Like all chromates and dichromates, its chromium is in the hexavalent state. It is very soluble and strongly reactive both as an acid and as an oxidizing agent Chromic acid (H2 CrO 4) oxidizes alcohols in aqueous solutions of sodium dichromate. It reacts with alcohols to form a chromic ester in which the alcohol oxygen atom bridges the carbon and chromium atoms. Thus, the ester forms by nucleophilic attack of the alcohol's oxygen atom on the chromium atom.

The anodizing process builds a basic oxide layer which supports a tubular cell structure. This structure is then generally sealed in hot water by conversion of the porous cell structure to the trihydrated aluminum oxide Chromic acid - Substance Information - ECHA NB: Registration status and tonnage The REACH Registered substance portal was updated on 9th November 2020; the REACH registered factsheets were further updated on 21st December 2020.

Chromium trioxide (CrO. 3), in varying percentages by weight, is commonly used to produce chromic acid. This chromic acid solution has the potential to be emitted as an aqueous mist from chrome-plating processes. However, while occupational exposure may be likely. Chromic acid is a strong oxidizing agent, used to oxidize many classes of organic compounds, the most common of which is alcohols. There are two generalizations that help understand oxidation of alcohols using chromic acid. 1. Any alcohol containing at least one alpha hydrogen is oxidized by chromic acid, meaning tertiary alcohols are not oxidized by chromic acid. 2. Any organic product formed.

Chromic acid plating solution is used in the electroplating of metals for making surfaces decorative and corrosion resistant. There are several recipes for making the plating solution.
