Question

A solution of sodium thiosulfate, Na₂S₂O₃, is 0.2851 M. 14.68 mL of this solution reacts with 8.62 mL of I₂ solution. What is the molarity of the I₂ solution?

2(Na₂S₂O₃) + I₂↔Na₂S₄O₆ + 2(NaI)

0.243

37.69 mL of the I₂ solution from above is required to titrate a sample containing As₂O₃. Calculate the mass of As₂O₃ (197.8 g/mol) in the sample.

As₂O₃ + 5(H₂O) + 2I₂ → 2(H₃AsO₄) + 4HI
