A galvanic cell based on the above reaction is constructed according to the generic sketch of a galvanic cell shown in the picture attached below.
1a) Choose the letter from the picture which best describes the following:
Solution containing IO3−, I2 and source of H+
Pt cathode
1b) which of the following overall, balanced, spontaneous reaction is occurring in this (standard) cell?
12H+(aq) + 2IO3−(aq) + 10Fe2+(aq) → 10Fe3+(aq) + I2(s) + 6H2O(l)
2IO3−(aq) + 10Fe2+(aq) → 10Fe3+(aq) + I2(s) + 6H2O(l)
12H+(aq) + 2IO3−(aq) + 2Fe2+(aq) → 2Fe3+(aq) + I2(s) + 6H2O(l)
10Fe3+(aq) + I2(s) + 6H2O(l) → 12H+(aq) + 2IO3−(aq) + 10Fe2+(aq)
1c) true or false?
