A.- An old tablet of vitamin C weighed 1.022g. It was dissolved in 500mL water, and a 25.0mL aliquot of this solution required 22.6mL of .005M I2 solution to oxidize it. Calculate the mg vitamin C in the tablet. B.- The strenght of an I2 solution may be verified by reacting the I2 with thiosulfate (S2O3)2- I^2+2(S2O3)^2- -> 2I^-+(S4O6^)2- 15.0 mL of an iodine solution of unknown molarity was titrated against a 0.001M solution of S2O3^2-. The blue black iodine-starch complex just disappeared when 20.2 mL of thiosulfate was added. What is the exact molarity of the I2 solution?.
