Which acid must be added to potassium dichromate to acidify it?

Potassium Dichromate (VI) can be acidified with sulphuric acid AND hydrochloric acid!
Note that another common oxidising agent ' Acidified Potassium Manganate (VII)' is sometimes used although this one can only be acidified with sulphuric acid not hydrochloric as the Manganate (VII) oxodises the Cl- ion instead!

What is the formula for acidified potassium dichromate?
This is a mixture of 2K+ and Cr2O72- ions in strong sulfuric acid, made from potassium chromate.2CrO4- + 2H+ ----> Cr2O72- + H2Ochromate-yellow -> dichromate-orangeNote:Potassium ions do NOT react, they are tribune-ions
Why is sulfuric acid added to sodium ethanedioate and hydrated ethanedioic acid?
to acidify the solution so that it can become a good oxidising agent
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.
What is the formula of acidified potassium permanganate?
There is not one formula for acidified potassium permanganate, it is a mixture, not a pure compound. Next to water it contains: H+ and K+ and MnO4- Warning: Do NOT use hydrochloric acid to acidify!
What is the chemical reaction of potassium dichromate with nitric acid?
K2Cr2O7 + 5HNO3 = 2KNO3 +Cr2(NO3)3 +5/2H2O + 9/2[O]
What is the name for H2Cr2O7 acid?
H2Cr207 is also known as chromic acid.
