Ozone (O3) is a colorless gas with a pungent odor. It can be generated by passing a high-voltage electric spark through air. O3 can be analyzed by its stoichiometric reaction with I- in neutral solution: O3 + 3I- + H2O → O2 + I3- + 2OH- (The reaction must be carried out in neutral solution. In acidic solution, more I3- is made than the preceding reaction indicates.) A 1.00-L bulb of air containing O3produced by an electric spark was treated with 25 mL of 2 M KI, shaken well, and left closed for 30 min so that all O3 would react. The aqueous solution was then drained from the bulb, acidified with 2 mL of 1 M H2SO4, and required 29.33 mL of 0.050 44 M S2O32- for titration of the I3-. Calculate the mass of O3 in the 1.00-L bulb.
