A cell consisting of a chromium strip and a lead wire, immersed in 1 M aqueous solutions of Cr(NO3)3 and Pb(NO3)2, respectively, was constructed. It was found that chromium strip depleted and certain solid deposited on the lead wire. Which of the following statement(s) is/are TRUE about the cell? O A. Crst was oxidized while Pb<+ was reduced. 2+ B. Cr served as the anode while Pb served as the cathode. C. Electrons flow from the lead wire to the chromium strip. O D. All of the choices
