In three 100 mL volumetric flasks, sequentially dilute the standard stock solution by pipetting aliquots of 1.00, 2.00, 5.00, into them, add 20.00 mL of ISA to each, and dilute to mark with water and mix. In a fourth but 250 mL volumetric flask, pipet a 25.00 aliquot of the stock solution, add 50.00 mL of ISA, and dilute to mark with water and mix. (You will need the extra volume of this most concentrated solution for further studies.) Record your actual standard concentrations accounting for the dilution as Cstd1, Cstd2, Cstd3, and Cstd4, respectively.
