2. You are provided with KIO3, how much do you need to weigh out and in what volume to give you what you require for the standardization? Note you only need enough to perform the titration but you need to weigh out an amount that will give you enough significant figures to be able to give you the correct molarity solution (4.167 x 10-3 M).
