Question

Part 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 iron-silver voltaic cell. Indicate the physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. Use (aq) for an aqueous solution. Do not forget to add electrons in your reaction.

Express your answer as a chemical equation.

PArt 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 iron-silver voltaic cell. Indicate physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. Use (aq) for an aqueous solution. Do not forget to add electrons in your reaction.

Express your answer as a chemical equation.

Explanation / Answer

the reduction potentials for iron and silver are

Eo Ag+/Ag = 0.80 V

Eo Fe+3/Fe = -0.04

electrode wit high red potential acts as cathode

so

silver is cathode

iron is anode

Part A :

at anode oxidation takes place

so

Fe (s) ----> Fe+3 (aq) + 3e-

Part B :

at cathode reductiont takes place

so

Ag+ (aq) ----> Ag (s) + e-
