In the lab, 0.115g of an unknown lipid was combined with 5.0mL of Chloroform and 10.0mL of Hanus iodine solution and store in the dark for 30 minutes. After the 30 minutes, 4.0mL of 15% KI solution and 40.0mL of water was added to the solution. The solution was titrated with 0.09787M Sodium Thiosulfate (Na2S2O3). When the solution became yellow, a few drops of 1% starch solution was added. The titration was continued until the solution was colorless. A total of 8.84mL of Sodium Thiosulfate was used until the solution was colorless.
The questions asks to calculate the iodine number for the lipid.

In preparing the sodium thiosulfate solution, the solid Na2S2O3x5H2O is not dried. Will this oversight cause the reported molar concentration of the standard Na2S2O3 solution to be too high, too low or unaffected? Explain.
4.60 mol of solid A wasplaces in a sealed 1.00 L container and allowed to decompose into gaseous B and C. The concentration of B steadily increased until it reached 1.10M where it remained constant.
