We are given an environmental engineer takes an air sample that hasbeen polluted with Sulfur Dioxide. The sample size is 500 mLat 700 torr and 38 Degree C. then we are given the unbalanced equationsSO2(g) + I2 (aq) + H2O (l) reactsto HSO4 -(aq) + I - (aq) + H + (aq) and also I2(aq) + S2O32-(aq) reacts toI-(aq) + S4O6 2- (aq)we also add 20.00 mL of 0.01017 M I (aq) What is the volume % of Sulfur dioxide in the air sample?
