What is the charge of dichromate?
Potassium Dichromate K2Cr2O7 is neutral.
Symbol for dichromate?
The formula of the dichromate ion is Cr2O72-
What is the oxidation number of Cr is acidified potassium dichromate?
The oxidation number of Cr in acidified potassium dichromate (K2Cr2O7) is +6. This is because each oxygen atom has an oxidation number of -2, and the overall charge of the dichromate ion is -2.
What is Na2CrO4 3H2O?

What ions are present in NH42Cr2O7?
The compound NH4₂Cr₂O7, known as ammonium dichromate, contains two ions: the ammonium ion (NH4⁺) and the dichromate ion (Cr2O7²⁻). Each formula unit of ammonium dichromate consists of two ammonium ions and one dichromate ion, balancing the overall charge of the compound. The ammonium ion carries a +1 charge, while the dichromate ion carries a -2 charge.
What is the formula for patassium dichromate?
The chemical formula of potassium dichromate is K2Cr2O7
Why are there 7 oxygen's in ammonium dichromate?
The dichromate ion is Cr2O7-2. Ammonium dichromate is two ammonium ions and one dichromate ion (to balance charges- ammonium has a +1 charge and dichromate has a -2 charge): (NH4)2Cr2O7. Therefore, ammonium dichromate would contain 7 oxygen atoms.
What is the oxidation number of Cr is acidified potassium dichromate?
The oxidation number of Cr in acidified potassium dichromate (K2Cr2O7) is +6. This is because each oxygen atom has an oxidation number of -2, and the overall charge of the dichromate ion is -2.
