Due to Chromium(VI) atoms
Potassium dichromate can be separated from water by a process of crystallization. This technique involves heating the potassium dichromate solution to a temperature just below the boiling point. As the solution cools, the potassium dichromate begins to crystallize out of the solution, allowing it to be filtered out and collected. The remaining liquid can then be discarded.
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.

Potassium Dichromate K2Cr2O7 is neutral.
The valency of dichromate ion (Cr₂O₇) in ammonium dichromate (NH₄)₂Cr₂O₇ is 6. This is because the two chromium atoms each have a valency of 6 in the dichromate ion, which is balanced by the two ammonium ions with a valency of 1 each.
The chemical formula of potassium dichromate is K2Cr2O7
The name for K2Cr2O7 is potassium dichromate.
The formula of the dichromate ion is Cr2O72-
