1. A triiodide solution was being examined by coulometry. The instrument measured 33.7 coulombs from the quantitative reduction of triiodide to iodide ion for a 10mL solution. Compute the concentration of triiodide in the solution.
2. For the examination in problem, presume the triiodide itself was generated from hydrogen peroxide. The original hydrogen peroxide solution had been diluted from 100mL to 250mL, and then a 10mL sample of this diluted solution was examined. From the 33.7 Coulombs measured, compute the concentration of hydrogen peroxide in the original solution.
