Take 20g of Potassium Dichromate powder and make a paste using small volume of water. To this add 300ml of concentrated Sulphuric acid with lot of care. Your Chromic Acid is ready. Use only Glass appartus for preparation and storage of chromic acid.
Use rubber gloves while handling chromate and acid.
Chromic 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.
The solution doesn't change colour for chromic acid will not react with a tertiary alcohol, therefore it remains a light shade of orange
Because chromic acid is an oxidizing agent.
I like to believe that I am correct in saying... Chromous Acid. Chromite being the polyatomic ion.

Hypochlorous acid is a stronger oxidant than Chromic acid

chromic acid
To prepare a buffer solution which may be acidic. Titrate ethanoic acid (weak acid) with sodium ethanoate(salt).
take 276 gm of salicylic acid in 1000 ml water to prepare 2M solution of the salicylic acid.
pl. suggest how to prepare 50 sulphuric acid
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...)
