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.

How is sodium chromate prepared?
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.
What is chrome used for?
the word chemical equation islead nitrate + sodium chromate --> sodium nitrate + lead chromate
What is chrome yellow used for?
the word chemical equation islead nitrate + sodium chromate --> sodium nitrate + lead chromate
What is the chemical name of the formula NaCro4?
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.
What is Na2CrO4 3H2O?
Na2Cr2O7 (the formula is not Na2CrO7) is sodium dichromate. Na2CrO4 is sodium chromate.
What is the formula for sodium chromate?
Na2CrO4
Could sodium chromate be used instead of potassium chromate?
Yes, because chemical properties of sodium and potassium ions are nearly same.
