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.

Answer 1

a) 2KI + O₃ + H₂O ----> I₂ + O₂ + 2KOH

b) Ozone concentration = 0.246 ppb

Step-by-step explanation:

Concentration of O₃ in air in ppb = 2.46/10 = 0.246 ppb
