Question
(Redox) Titration Problem
Testing for the concentration of ozone dissolved in water can be accomplished by titrating a known volume of the solution to be tested with a standardized potassium bromide solution. The reaction that takes place forms oxygen gas and the bromate ion, which can be detected spectroscopically. In a particular experiment, a 25.00 mL ozone containing solution was titrated with 37.41 mL of 0.3290 M potassium bromide. Determine the concentration of ozone in the original solution.
Explanation / Answer
(MV)Ozone=(MV)KBr
(M)Ozone=(MV)KBr/ (V)Ozone = (37.41 x 0.329)/ 25
(M)Ozone=0.4923 is the concentration of ozone in the original solution.
