help me please?!

Score/25 ame Date The accuracy of this experiment depends on result in an erroneously an good technique. Would the following technique errors gh or an erroneously low calculated molarity of an iodine solution? Briefly explain your reasoning for each answer a) Improper use of the autopipette results in less than 10 mL of the standardizing solution being dispensed. b) When filling the buret with iodine solution, you left an air bubble in the buret tip. The bubble was released during your first standardization titration c) After completing the tration, you noticed droplets of titrant clinging to the inner wall of your buret. 4. Explain why is it important to ensure that a titration is completed at the lightest color possible? whether your data indicates that the Siena Drink Mix was labeled with the correct Vitamin C content DATE PUT T THE BACK C THE

Explanation / Answer

a) calculated molarity is less than the expected.

b)the reading for titration will be more than the expected, thus molarity will be more than expected value

c) The value of titrant used reading will be higher, the molarity will be more than expected

4. the addition of even one extra drop results in large variation in result. thus it is important to obtain endpoint as lightest color possible
