Question

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 the following.

mmol of S2O32- mmol mmol of S2O82- mmol molar ratio of S2O32- relative to S2O82-

Explanation / Answer

NC State chem lab 202? haha but anyway if you look at the lab worksheet it gives you the molarities of the compounds, the S2O3 is .0050 and the S2O8 is .100 the initial amounts are 10mL of S2O3 and 20mL of S2O8 so:
a) .050mmol
b) 2.00mmol
for molar ratio you just divide a by b:
c) .025
