Answer to Question #85320 in General Chemistry for makinzie Kellerman

Question

Directions: Using the provided stock solutions, create six solutions that have varying concentrations of
potassium iodate (KIO3) and a concentration of 0.01 M for sodium bisulfite (NaHSO3). You will want
some solutions to have more moles of KIO3 than NaHSO3 and others to have fewer moles of KIO3 than
NaHSO3.
Dilute each component separately and then mix the components together when you are ready. As soon
as the solutions are mixed, the reaction will begin. You will want to maintain a constant total volume of
solution to be 4 mL. You will need to add 5 mL of starch solution to one of your solutions as you are
diluting the solution.

I already know how to serially dilute the KIO3, but I'm confused how I can keep the concentration of the solution at 1.0 as I dilute the solution.
