Chem. 1A Chapter 13 Worksheet 1. Rationalize the trend in water solubility for the following simple alcohols: Alcohol Solubility (g/100 g H 2 O at 20°C) Methanol, CH 3 OH Soluble in all proportions Ethanol, CH 3 CH 2 OH Soluble in all proportions Propanol, CH 3 CH 2 CH 2 OH Soluble in all proportions Butanol, CH 3 CH 2 CH 2 CH 2 OH 8.14 Pentanol, CH 3 CH 2 CH 2 CH 2 CH 2 OH 2.64 Hexanol, CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 OH 0.59 Heptanol, CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 CH 2 OH 0.09 2. Which solvent, water or carbon tetrachloride, would you choose to dissolve octane (C 8 H 18 )? 3. The solubility of nitrogen in water is 8.21 x 10 -4 mol/L at 0°C when the N 2 pressure above water is 0.790 atm. Calculate the Henry's law constant for N 2 in units of L atm/mol. 4. A solution is prepared by dissolving 50.0 grams of cesium chloride (CsCl) in 50.0 grams water. The volume of the solution is 63.3 mL. What is the mole fraction of this solution? 5.
