Question

The concentration of ozone in ground-level air can be determined by allowing the gas to react with an aqueous solution of potassium iodide, KI, in a redox reaction that produces molecular iodine, molecular oxygen, and potassium hydroxide. Assume 1 atm and 25.0 C

a) Deduce the balanced reaction for the overall process

b) Determine the ozone concentration, in ppb, in a 10.0 L sample of outdoor air if it required 17.0 ug of KI to react with it.
