Draw a diagram of the Voltaic cell described and label as indicated.   Cr2O7(aq)  +  14H+(aq) + 6I-(aq)  → 2Cr2+(aq)  +  3I2(s) + 7H2O(l)   This is a spontaneous redox reaction.  A solution containing K2 Cr2  O7  and H2 SO4  is poured into one beaker and a solution of KI is poured into another beaker.  A salt bridge is used to join the beakers.  A metallic conductor that will not react with either solution (such as Pt foil) is suspended in each solution, and the two conductors are connected with wires through a voltmeter or some other device to detect an electric current.  The resultant voltaic cell generates an electric current.  Indicate the reaction occurring at the anode, the reaction at the cathode, the direction of electron migration, the direction of ion migration, and the signs of the electrodes.
