what is chromate chemistry
Chromate salts contain the chromate anion, CrO 4 2â . Dichromate salts contain the dichromate anion, Cr 2 O 7 2â . They are oxoanions of chromium in the oxidation state +6. They are moderately strong oxidizing agents.In an aqueous solution, chromate and dichromate ions can be interconvertible.ichromate salts contain the dichromate anion, Cr 2 O 7 2â .
