Standardization of a Solution A 50.00 mL aliquot portion of 0.01020 M KIO3 solution was transferred into a conical flask. After adding 2.0 g KI and 2 mL of 6M HC1, the mixture was titrated with 31.32 mL of the Na2S2O3 solution to the starch end point. Calculate the number of mmoles of IO3-. mmoles 103- How many mmoles of 12 was released after the addition of KI? mmoles I₂ How many mmoles Na2S2O3 reacted with the 12 produced? mmoles Na2S2O3- What is the molarity of the Na2S2O3 solution?

Account for this fact: Mixing 50 mL of methanol with 50 mL of water produces a solution with a volume slightly less than 100 mL. Methanol evaporates during the mixing. During hydration, methanol molecules decrease in volume. Owater evaporates during the mixing. Water molecules interact extensively with methanol molecules. New Tab a. Account for this fact: Although methanol (CH3OH) (bp, 64.7 °C) has a higher molar mass than water (bp, 100 °C), the alcohol has a lower boiling point. O Methanol has non-polar carbon chain. Methanol is an organic compound and water is an inorganic compound. O Water has two O-H bonds and methanol has only one. Methanol has more hydrogen atoms per molecule. +
