Solved: A method used by the U S. Environmental Protection

Chapter , Problem 99AE

(choose chapter or problem)

A method used by the U.S. Environmental Protection Agency (EPA) for determining the concentration of ozone in air is to pass the air sample through a "bubbler" containing sodium iodide, which removes the ozone according to the following equation:

\(\mathrm {O}_{3}(g)+2\ \mathrm {NaI}(aq)+\mathrm {H_{2} O}(l) \longrightarrow \mathrm {O}_{2}(g)+\mathrm I_{2}(s)+2\ \mathrm {NaOH}(aq)\)

(a) How many moles of sodium iodide are needed to remove \(5.95 \times 10^{-6}\) mol of \(\mathrm O_3\)? (b) How many grams of sodium iodide are needed to remove  of \(\mathrm O_3\)?
