Question
The molecular iodine (12) in betadine is susceptible to decomposition if exposed to direct sunlight, which
lowers the concentration of 12 solution. After performing the standardization step in home experiment 9, a
student leaves their betadine solution in direct sunlight for several hours before coming back to perform the
titration of ascorbic acid in orange juice. Assuming that the concentration of 12 is reduced by the sunlight, how
would this affect the measured value of the concentration of ascorbic acid in the orange juice?
The measured concentration of ascorbic acid would be higher
The measured concentration of ascorbic acid would be lower
There is not enough information to determine the affect on the measured concentration of ascorbic acid
The measured concentration of ascorbic acid would be unaffected
