If you go back and try this exercise again the values will change. Read the question carefully! Answer:1. A stock solution of I2 is standardized using a 0.1430 g sample of pure ascorbic acid. The titration to the starch endpoint required 25.45 mL of the I2 solution. Calculate the molarity of the I2 solution. 2. A vitamin C tablet was divided into three equal mass portions. One portion was crushed into a fine powder, dissolved in water, and titrated with the standardized solution from question 2 (above). The titration to the endpoint required 27.60 mL of the I2 solution. Calculate the number of milligrams of vitamin C that are in the original tablet.SEE MORE QUESTIONS
