IO 3 (aq) + Fe 2+ (aq) Fe 3+ (aq) + I 2 (s) A galvanic cell based on the above r

Question

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:

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

Pt anode

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

10Fe3+(aq) + I2(s) + 6H2O(l) 12H+(aq) + 2IO3(aq) + 10Fe2+(aq)   ( I thought it was this one but not totally sure)
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)

True or 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

The correct eqaution for the Galvanic cell here would be ,

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

True or false statements,

The salt bridge is labelled 'C' - True

the solution in tube 'B' must not conatin an electrolyte for the cell to operate - False

The salt bridge in intended to allow counter ions to flow between the two compartments - True

The salt brdige disrupts the electrical circuit while permitting mixing of the solutions in the anode and cathode compartments - False

Tube 'B' hinders Fe2+ ions from migrating to the other comparment and reacting directly with the iodate solution - True
