Unformatted text preview: mary standard solution. Now, we will examine the volumes of titrant and sodium thiosulfate used in each trial. Your titration volumes of the sodium thiosulfate solution should be approximately 20 - 30 mL. For each trial, enter the precise volume in mL of sodium thiosulfate solution used in the titration of your potassium iodate solution (e.g. 20.34 mL). Using the volumes of sodium thiosulfate solution you just entered and the molarity of the potassium iodate primary standard solution, calculate the molarity of the sodium thiosulfate secondary standard solution for each trial. Enter your calculated molarity of the sodium thiosulfate solution for each of the trials. Be sure to enter your calculated molarities in the corresponding order that you entered your sodium thiosulfate volumes previously. The sodium thiosulfate volume you entered for entry #1 above should correspond to the sodium thiosulfate molarity that you enter for entry #1 here. Use three significant figures. The molarity of the sodium thiosulfate solution is taken as the avera...
