Asked by Alexander
A student mixed the following reactants, using the general procedure for the experiment:
10.0 mL of 0.10 M KI, 10.0 mL of 0.0010 M Na2S2O3, 20.0 mL of 0.040 M K2S2O8, and 10.0 mL of 0.10M HCl. It took about 75 seconds for the mixture to turn blue.
a. By using the dilution equation (M1V1=M2V2), calculate the concentrations of each
reactant in the mixture after all of the solutions have been combined:
[I-] = ________ [S2O32-] = ________ [H+] = ________
