The dichromate ion has the charge -2.
How chromate ions are converted into dichromate ions?
In an acidic solution chromate ions are converted into dichromate ions.
How many oxygen atoms does dichromate have?
Dichromate is Cr2O7^2- so it has 7 oxygen atoms in one molecule
What is the formula for potassium dichromate?
k2cr2o7K2Cr2O7
How do you convert a chromate ion to dichromate?
(Cr2O7)2- + H2O -> CrO4- + 2H+ Chromate is yellow and Dichromate is orange. If the solution is yellow, then by LeChatlier's Principle, if an acid is added, then the Dichromate will form predominately.

Please Help me in finding the valency of dichromate in ammonium dichromate?
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.
