Hope my answer is helpful. :)
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
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.
