Question
Suppose you want to study the influence of IO3- concentration on the rate of the reaction used in Part A. Which of the following procedures would be appropriate? a. Use different amounts of KIO3 solution with a constant amount of water and a constant amounts of NaHSO3 solution. b. Use different amounts of KIO3 solution, constant amounts of NaHSO3 solution, and different water amounts to give a constant total amount. c. Use different amounts of KIO3 solution, different amounts of NaHSO3 solution, and constant amounts of water. *Original reaction 3HSO3- (aq) +IO3- --> 3HSO4- (aq) + I- (aq) I believe the answer is b and total volumes should remain consistent throughout the experiment as we did in the original experiment, but I'm not certain.
Explanation / Answer
(b) you are exactly corect.
To maitain constant concentraion of NaHSO3 we need to adjust the amount of water inaddition to taking the different amounts of KIO3 solution.
