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
What is the color of dichromate?
Depending on its oxidation state and the environment it is in, it can be.Chromium colors include black, red, orange, green, and yellow.Chromate salts contain the chromate ion, CrO4-2, and have an intense yellow color.Dichromate salts contain the dichromate ion, Cr2O7-2, and are an intense orange color.Chromic acid ( chromium trioxide, CrO3) is redChromic oxide is a dark greenAs a plated metal chromium is essentialy colorless.
How do you prepare chromic acid reagent?
alwase
What is H2CrO2?
I would say per-chromic acid.
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.
How do you mak sulfochromic acid?
mix 12 mL of sat'd aqueous solution of chromium trioxide acid with 2.7L of H2SO4
What is the molecular weight of chromic acid?
The molecular weight, also referred to as molar mass, of chromic acid is 118.01 grams/mol since the atomic weight of two Hydrogen is 1.0079, Chromium is 51.996, and Oxygen is 15.999.
What is the oxidation for chromic acid?
Oxidation state of: Chromium = +6 Oxygen = -2 Hydrogen = +1
What is the name of the acid H2CrO4?
Chromic Acid
How you will prepare chromic acid solution?
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.
What medical word sounds like kro-mik?
"Chromic" is the only word I can think of which, medically speaking, could be related to chromic acid, or hexavalent chromium, poisoning. The stuff is used in chrome-plating, and is carcinogenic.
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.
WHAT IS H2Cr?
chromic acid
What is the name Cr2O5?
Cr2O3 is usually considered to be an ionic compound, in which instance its proper name is "chromium (III) oxide" (now preferred) or "chromic oxide" (more often used about 50 years ago.) If Cr2O3 is considered to be covalently bonded, its proper systematic name would be "dichromium trioxide." Some chemists also call it "chromic acid anhydride."
