Chromic acid is found on List A, which contains most pesticides that are used on foods and, hence, have a high potential for human exposure. List A consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA '88.
Chromic acid, H 2 CrO 4, is a strong acid and a reagent for oxidizing alcohols to ketones and carboxylic acids. For fairly mundane reasons owing primarily to safety and convenience, chromic acid tends to be made in the reaction vessel as needed (through addition of acid to a source of chromium), rather than being dispensed from a bottle.
CHROMIC ACID SOLUTION reacts rapidly with many materials including common combustibles, often causing ignition. CAUTION: THE USE OF CHROMIC ACID IS CONSIDERED A HEALTH HAZARD AND IS CONSIDERED A CARCINOGEN. Chromium forms both the chromous (Cr2+) and chromic (Cr3+) compounds that are highly colored. Chromic acid (H2 Cr O4) is a strong acid because hydrogen ions completely disassociate in the ...

Tetraoxochromic acid or Chromic(VI) acid are other names for chromic acid. It’s normally made by mixing concentrated sulphuric acid (H2SO4) with a dichromate that includes a number of compounds and solid chromium trioxide. Sulphuric acid (H2SO4) and molecular chromic acid (H2CrO4) are both strong acids, but only the first proton is easily lost.
Chromic acid is formed when chromium trioxide reacts with water. Chromium trioxide is crystalline, light red or brown in colour and is deliquescent and fully soluble in water. Chromic acid is a very weak acid and its salts can be dissociated even by acetic acid.
What does chromic acid react with? Chromic acid (H 2 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. In an aqueous acid solution, chromic acid converts aldehydes to carboxylic acids.
