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.

What is the difference between potassium chloride and potassium nitrate?
The difference between potassium nitrate and potassium sulphate is that the potassium nitrate is superior to potassium sulphate. The potassium nitrate has high solubility while the potassium sulphate has moderate solubility.
How do you make sodium chromate?
Chromic acid and ammonium hydroxide react to yield ammonium dichromate followed by crystallization to yield a pure crystalline product. H2Cr2O7 + 2NH4OH ==> (NH4)2Cr2O7 + 2H2O Reactions with the dichromate ion should be avoided if possible due to the toxicity and possible carcinogenic nature of hexavalent chromium. Groundwater contamination with hexavalent chromium was the subject of the Hollywood movie Erin Brockovich.
