The following oxidation-reduction reactions are used in electrochemical cells. Write them using cell notation. a) Write the net equation for the redox reaction that occurs in the voltaic cell: Sc(s) │Sc3+(aq) ║ Ag+(aq) │Ag(s) (Hint: Assume that the customary conventions were used in writing the cell diagram.) b) Draw a voltaic cell in which the displacement of silver ions from solution by aluminum metal occurs. Label the cathode, the electrons. Also, indicate the direction of the flow of cations and anions from the KNO3 (aq) salt bridge. Write an equation for the half-reaction occurring at each electrode, write a balanced equation for the overall reaction, and write the cell diagram.
