The correct answer is - The dichromate ion Cr₂O₇²⁻.
The Oxoanions of the metals are compounds in which the metals tend to form bonds with the available oxygen atom. Therefore, they exist in their highest oxidation states. It is stable in acidic medium and is also soluble in water.
In the Dichromate salts, the dichromate anion is represented as Cr₂O₇²⁻and the oxidation state of Chromium in it is +6. It acts as an oxidizing agent which is a little strong and but when compared with the chromate ion, the dichromate ions is a weaker base.
