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.
The chemical formula of sodium chromate is Na2CrO4.

Copper(II) chromate can be prepared by reacting a solution of sodium chromate with a solution of copper(II) sulfate. The resulting precipitate is then filtered and dried to obtain solid copper(II) chromate.
Sodium chromate usually does not contain any water molecules per formula. The formula for sodium chromate is Na2CrO4, which does not have any water molecules associated with it.

Sodium chromate is the name of the compound Na2CrO4.
That's sodium chromate. However, the correct formula would actually be Na2CrO4, because sodium is a +1 metal, and the chromate polyatomic has a -2 charge. Therefore it will require two sodium atoms.
Sodium chromate is prepared by adding caustic soda to Sodium Dichromate. Go on adding causting soda till the pH drops to 6. what we get is the solution of Sodium chromate and you can evaporate, crystallise and filter.

Na2CrO4
Sodium chromate, a yellow crystalline solid, is the chemical compound Na2CrO4. Its hydrated form, Na2CrO4·3H2O, contains three molecules of water per molecule of sodium chromate. This compound is water-soluble and is commonly used in laboratory applications.
The compound with the formula Na2CrO4 is called sodium chromate. It is a yellow crystalline solid that is commonly used in industrial processes such as producing pigments and as a corrosion inhibitor.
When sodium chromate and lead nitrate are mixed, a yellow precipitate of lead chromate is formed, along with sodium nitrate remaining in solution.
