Unformatted text preview: ot be the person in your lab room that causes these problems! Below is a rough outline of the titration procedure; you should elaborate and provide further details such as the amounts used of each reagent in your laboratory report. The outline of the procedure also contains some important information that will assist you in performing an effective titration. 1. Preparation of the potassium iodate solution. • You should dilute the sodium thiosulfate solution to approximately 0.05 M. This will give you reasonable volumes for your titrations. Plan on making about 300 mL of the sodium thiosulfate solution. 2. Preparation of the iodine solution. • Prepare 250 mL solution of potassium iodate (approximately 0.01 M), and transfer a measured amount of this solution into the titration flasks. Prepare the solution in a 250 mL volumetric flask and share the solution between you. Calculate the final molarity of the potassium iodate to three significant figures. Be sure to use volumetric glassware to transfer this iodate solution into your titration flask This method will speed up your titrations in two ways. You will sp...
