Initial Concentration = concentration after mixing (time elapsed = 0 s) Concentr

Initial Concentration = concentration after mixing (time elapsed = 0 s)
Concentration Change = concentration change at the moment the starch indicator changes color
Percent concentration change = Concentration Change/Initial Concentration 100%
Hint: S2O32- is completely used up. Starting with the concentration of S2O32- used up first calculate the concentration of I2 consumed by S2O32- and then calculate the concentrations of each reagent used based on the stoichiometry in equation (1).
