Consider a chromium-silver voltaic cell that is constructed such that one half-cell consists of the chromium, Cr, electrode immersed in a Cr(NO3)3 solution, and the other half-cell consists of the silver, Ag, electrode immersed in a AgNO3 solution. The two electrodes are connected by a copper wire. The Cr electrode acts as the anode, and the Ag electrode acts as the cathode. To maintain electric neutrality, you add a KNO3 salt bridge separating the two half-cells. Use this information to solve Parts B, C, and D.What is the net cell reaction for the chromium-silver voltaic cell?

  1. Were are parts B, C, and D.
    Rxn is (add the two half cells below)
    Cr(s) ==> Cr^3+ + 3e
    Ag^+ + e ==> Ag(s)
    --------------------
    Cr(s) + 3Ag^+ ==> 3Ag(s) + Cr^3+
