The purity of hydrazine, N2H4 is determined by titration with iodine. A sample of the oily liquid weighing 1.4286 is dissolved in water and diluted to 1.00L in volumetric flask. A solution of 50.00mL aliquot is taken with a pipet and titrated with a standard iodine solution, requiring 42.41 mL. The iodine was standardized against 0.4123g of primary standard As2O3, by dissolving As2O3 in a small amount of NaOH solution, adjusting the pH to 8.0, and titrating, requiring 40.28 mL iodine solution. Calculate the percentage purity of the hydrazine.
