The d-and f-Block Elements

Solution:

Sodium dichromate is less soluble than potassium dichromate. Colour of sodium dichromate and potassium dichromate is orange. The chromates and dichromates are interconvertible in aqueous solution depending upon $pH$ of the solution. The oxidation state of chromate and dichromate is same.
