2. In half-cells, reduction occurs in the ______ while oxidation occurs in the _______.
3. In a galvanic cell, ��(�) oxidizes to form ��!"(��) while ��!" reduced to form ��(�).
a. Write the half reactions for this galvanic cell.
b. Provide its cell notation (line notation).
4. (a) Draw a diagram, (b) show balanced half-reactions, and (c) write the standard cell
notation (line notation) for a voltaic (galvanic) cell that consists of one half-cell with
a solid �� bar submerged in ��(��#)# solution, another half-cell composed on a solid
silver bar in ����# solution, and a ���# salt bridge. Measurement indicates that the
chromium electrode is negative relative to the silver electrode.
