The formula of the dichromate ion is Cr2O72-
The symbol for dichromate is Cr2O7^2-, indicating that it is a polyatomic ion composed of two chromium atoms bonded to seven oxygen atoms with an overall 2- charge.
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.
Potassium Dichromate K2Cr2O7 is neutral.
The chemical name of SnCr2O7 is tin(IV) dichromate.
silver dichromate

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 chemical name of SnCr2O7 is tin(IV) dichromate.
