A battery is constructed of Cr and Na2Cr2O7. The unbalanced chemical reaction when such a battery discharges is following :
Na2Cr2O7 + Cr + H+ gives Cr3+ +H2O + Na+
If one Faraday of electricity is passed through the battery during the charging, the number of moles of Cr3+ removed from the solution is :
