Question

Construction of a voltaic cell

Consider a chromium-silver voltaic cell that is constructed such that one half-cell consists of the chromium, CrCr, electrode immersed in a Cr(NO3)3Cr(NO3)3 solution, and the other half-cell consists of the silver, AgAg, electrode immersed in a AgNO3AgNO3 solution. The two electrodes are connected by a copper wire. The CrCr electrode acts as the anode, and the AgAg electrode acts as the cathode. To maintain electric neutrality, you add a KNO3KNO3 salt bridge separating the two half-cells. Use this information to solve Parts B, C, and D.
 
a) The half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell is the site of the reduction reaction.

Type the half-cell reaction that takes place at the anode for the chromium-silver voltaic cell. Indicate the physical states of atoms and ions using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. Use (aq) for an aqueous solution. Do not include phases for electrons.

b)The half-cell is a chamber in the voltaic cell where one half-cell is the site of an oxidation reaction and the other half-cell is the site of a reduction reaction.

Type the half-cell reaction that takes place at the cathode for the chromium-silver voltaic cell. Indicate the physical states of atoms and ions using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. Use (aq) for an aqueous solution. Do not include phases for electrons.
