TalkChromic acid Wikipedia
When hydrochloric acid is added to bichromate of potash, chromic acid is liberated. Like manganese, chromium forms two unstable acids, namely, chromic acid and dichromic acid. A saturated solution of chromic acid is also used for the same purposes.... Take a sample, periodically, and spot test with acid/1,5 diphenylcarbohydrazide reagent to make sure the chrome is all reduced. Then, add lime till the pH of a water suspension is between 10 and 12. Then, add lime till the pH of a water suspension is between 10 and 12.

Chromic acid provides the source of chromium ions in the bath. The chromic acid concentration may be varied over a wide range in order to obtain certain advantages for special applications. It is important, however, to maintain the proper chromic acid to sulfate ratio. The best practice is to establish the optimum concentration of chromic acid and maintain it at that level with regular

  • 2/07/2006 · Chromic chloride: May be prepared by dissolving hydrated chromium oxide in hydrochloric acid and evaporating off the liquid. It may also be prepared by adding, by weight, 1 part of either sodium or potassium dichromate to 6 parts of hydrochloric acid and gently heating for a few seconds to initiate the reaction. Chlorine gas will be evolved, so do this reaction is a well ventilated area.
  • The process is highly specialized, requires use of highly toxic, volatile, and carcinogenic elements (such as chromic acid and sulfuric acid), and produces very hazardous waste. Knowing how to chrome plate may interest you, but you are advised to consider specific safety concerns.
