Question
Consider the redox reaction:
I2 + 2(S2O3^2-) <==> 2I^- +S4O6^2-
thiosulfate tetrathionate
a) Identify the oxidizing agent on the left side of the reaction and write a balanced oxidation half-reaction.
b) Identify the reducing agent of the left side of the reaction and write a balanced reduction half reaction.
c) How many coulombs of charge are passed from reductant to oxidant when 1.00g of thiosulfate reacts?
d) If the rate of reaction is 1.00g of thiosulfate consumed per minute, what current (in amperes) flows from reductant to oxidant?
Explanation / Answer
I2 (S2O3^2-
