In organic chemistry, dilute solutions of hexavalent chromium can be used to oxidize primary or secondary alcohols to the corresponding aldehydes and ketones. Tertiary alcohol groups are unaffected. Because of the oxidation is signaled by a color change from orange to a blue-green, chromic acid is used as a qualitative analytical test for the presence of primary or secondary alcohols.

Preparation of chromic acid from chromium trioxide?
A general rule of thumb in chemistry is that metal oxides in water will form acids: CrO3+H2O -> H2CrO4. In fact, Chromium Trioxide is often sold as Chromic anhydride, that is, the anhydride of Chromic acid (take away water from Chromic acid, and you have...)
Is H2CrO4 weak acid?
Chromic acid, H2CrO4, is a strong acid.
What is the solvent for aluminium oxide?
Phosphoric acid and chromic acid
How do you prepare chromic acid reagent?
alwase
An unknown carbonyl compound tested positive when mixed with chromic acid solution it also showed positive results in the iodoform test draw the struture of this compound?
acetic acid
Chromic acid test in alcohols?
Lucas Test is better.
What is the name of the acid H2CrO4?
Chromic Acid
What does chromic acid test and lucas test indicate?
if it is a primary, secondary or tertiary alcohol
Why does chromic acid react with aldehydes?
Because chromic acid is an oxidizing agent.
What is the main advantage of the hypochlorus acid compared with chromic acid?
Hypochlorous acid is a stronger oxidant than Chromic acid
What is the name formula for HCrO4 as acid?
I like to believe that I am correct in saying... Chromous Acid. Chromite being the polyatomic ion.
How chromic acid is prepared from potassium dichromate and sulphuric acid?
Chromic acid is the acid in chromic acid. The chemical formula is H2CrO3 (Not correct)Added & Corrected:Often the species are assigned the formulas H2CrO4 (dihydrogen chromate) and H2Cr2O7 (dihydrogen dichromate).The anhydride of these "chromic acids" is chromium trioxide, also called chromium(VI) oxide (2CrO3=Cr2O6).Regardless of its exact formula, chromic acid features chromium in an oxidation state of +6 (or VI), the highest known.
