I find myself having to post the same questions multiple times because people that answer it just take a guess and then my question never gets answered. Thanks for your help.

IO3(aq) + Fe2+(aq) Fe3+(aq) + I2(s)

A galvanic cell based on the above reaction is constructed according to the generic sketch of a galvanic cell shown below:

Please let me know if the image doesn't show. I will then provide a link.

The overall, balanced, spontaneous reaction occurring in this (standard) cell is:

10Fe3+(aq) + I2(s) + 6H2O(l) 12H+(aq) + 2IO3(aq) + 10Fe2+(aq)
2IO3(aq) + 10Fe2+(aq) 10Fe3+(aq) + I2(s) + 6H2O(l)
12H+(aq) + 2IO3(aq) + 2Fe2+(aq) 2Fe3+(aq) + I2(s) + 6H2O(l)
12H+(aq) + 2IO3(aq) + 10Fe2+(aq) 10Fe3+(aq) + I2(s) + 6H2O(l)

Choose the label which best describes the following:
Solution containing Fe2+ and Fe3+

Pt anode

Answer True/False
The salt bridge is labeled 'C'.
The solution in tube 'B' must not contain an electrolyte for the cell to operate.
The salt bridge is intended to allow counter ions to flow between the two cell compartments.
The salt bridge disrupts the electrical circuit while permitting mixing of the solutions in the anode and cathode compartments.
Tube 'B' hinders Fe2+ ions from migrating to the other compartment and reacting directly with the iodate solution.

Explanation / Answer

12H+(aq) + 2IO3(aq) + 10Fe2+(aq) 10Fe3+(aq) + I2(s) + 6H2O(l)

please provide the link for diagram then i can answer second paer.
