A solution of lodine was standardized using 225 mg of arsenic trioxide (197.94 g/n) in which the primary standard consumed 4.57 ml of the solution. 200 mg of potassium dichromate (294.19 g/n) was also used in the standardization of sodium thiosulfate in which 4.12 of titrant was consumed. These two standard solutions were used in the assay of 0.95-g sample of sodium bisulfite. 50 ml of the iodine solution was added first and the excess iodine was titrated using 32.33 ml of sodium thiosulfate. Calculate the N of the iodine solution. Round off answers to four decimal places.

You measure 15.0 mL of the H2C2O4 solution with a 100-mL graduated cylinder and add it to a 125-mL Erlenmeyer flask. Then you add two drops of the indicator, phenolphthalein, to the oxalic acid solution in the flask. You dispense the NaOH solution from the buret into the flask (while swirling the flask) until you reach the endpoint. At the endpoint, the solution in the flask turns light pink. You repeat the titration two additional times for a total of three trials.
