Pre-lab Calculations: The reactant concentrations given in the procedure are not the concentra- tions of the solutions once everything is mixed together. Once the reactants are mixed, the volume of the overall solution increases to 50.00mL for all trials. You will need to use the dilution equation (M, V = M,V.) to calculate the concentrations of each reactant ion.

In this lab we will be expressing rate as a change in
concentration of reactants over time. In order to calculate this,
we need to know the initial concentrations of our reagents after
they are combined but before the reaction occurs. This is a
dilution process. Recall that the calculation for a dilution is
accomplished using the relationship M1V1 = M2V2.
If the [S2O3 2- ] is initially 2.49x10-4 M, and the reaction
takes 145 seconds for the solution to...
