1) Peroxydisulfate ion oxidizes iodide ion to triiodide ion, I3-. The reaction is S2O82- (aq) + 3I - (aq) ? 2SO42- (aq) + I3- (aq)
If the sulfate anion (SO42-) is formed at a rate of 0.040 M/min, what is the rate of formation of I3-? What is the rate of consumption of S2O82-? What is the rate of consumption of I-?
