In the method of initial rates that will be used in the experiment, you will measure the time it takes for the first small percentage of the reaction to occur. In our reacting system, this corresponds to the time it takes for the thiosulfate ion (S2O32-) to be used up (see background section of experiment for details). For this to work, the amount of thiosulfate anion should be small relative to the amount of persulfate anion.In order to verify this, use the amounts of solution suggested for Run #1 in Data Table A and find:
