potassium
Na2Cr2O7 (the formula is not Na2CrO7) is sodium dichromate. Na2CrO4 is sodium chromate.
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.
dichromate ion
Potassium chromate is K2CrO4 Potassium dichromate is K2Cr2O7
The name of SnCrO4 is Tin II Chromate or stannous chromate.
The dichromate ion has the charge -2.
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.
