A standard hydrogen electrode (SHE) is shown in the following figure. What are the standard conditions (A, B and X) for the SHE-cell Question 33.docx

Oxidation occurs at the (I) ………….. and reduction occurs at the (II) ………… in a voltaic cell        (I)       (II) (A)   anode    anode  (B)  cathode    cathode (C)  anode   cathode (D)  cathode   anode

Two half-cells are shown below: Fe2+(aq)  +  2e-   ↔  Fe(s)     Ecell = – 0.44 V Cu2+(aq)  +  2e-  ↔  Cu(s)    Ecell = +0.34 V Hint: The half-cell with the highest positive potential gets reduced. the other half-cell must get oxidized. Based on the cell voltage you received for question 21, what can you say about this cell?
