A sample of pure aniline was dissolved in HCl and diluted to 100 mL with `H_2O`. 20 " mL of " liquid was treated with 25 " mL of " 0.017 M `KBrO_3` and about 10 g KBr was added to form `Br_2`. After 10 min, an excess of KI was added and the liberated `I_2` was titrated with 12.92 " mL of " 0.12 M `Na_2S_2O_3`. Calculate the weight of aniline taken.
