About Chromic Acid
Chromic Acid usually refers to a collection of compounds formed via the dissolution of Chromium Trioxide in Sulfuric Acid, or via the acidification of Chromate/Dichromate solutions. It is a dark red, strongly corrosive liquid.
Since it contains chromium in its +6 oxidation state, it has strong oxidizing properties and a high redox potential. Hence, Chromic Acid has been used as a cleaning reagent for lab glassware, textiles, and metals, and an oxidizing agent in organic chemistry reactions. For a time, it was commonly used in musical instrument repair to brighten brass, and as a bleach in photograph development. The properties that lend this compound to these applications also increase its toxicity due to its increased ability to enter cells, so some industries have phased in out in favor of alternatives. It is generally available in relatively dilute solutions.
