A corrosive and strongly oxidizing acid existing only in solutions of chromium trioxide.
〔化〕铬酸
Chemical formula: H₂CrO₄
Example sentencesExamples
The most regularly employed oxidizing agent for this set of reactions is a mixture called chromic acid, a mixture of sodium or potassium dichromate and sulfuric acid.
A wide variety of electrolytes are used to produce the desired surface properties: chromic acid, sulfuric acid, and oxalic acid are the most common but borates, citrates and oxoacids are also sometimes used.
The paint spray workshop also contained two acetylene cylinders, two oxygen cylinders and two propane bottles as well as chromic acid and acetone.
After cleaning, the parts are etched or pickled in a chromic acid / nitric acid solution to remove any oxide layer or other chemical coatings not fully removed by alkaline cleaning.
Environments to be avoided include nitric acid; some metallic salts, such as ferric chloride and chromic acid; moist chlorinated hydrocarbons; and moist HN 3.
