Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points Each of the following samples was placed in 1 liter of water. I) 0.6 mol NaOH II) 0.7 mol KCl III) 0.5 mol Na 2 NO 3 IV) 1 mol of sugar Rank the solutions that are made in terms of increasing order of boiling point elevation. (Remember your solubility rules.) 1. III, I, IV, II 2. II, IV, I, III 3. IV, I, II, III correct 4. III, I, II, IV 5. IV, II, I, III Explanation: Colligative properties of a solution depend on the number of solute particles in solution, not the type. I) will have 1.2 mol of particles because NaOH completely dissociates in water. II) will have 1.4 mol of particles because KCl completely dissociates in water. III) will have 1.5 mol of particles because Na 2 CO 3 completely dissociates in water. IV) will have 1 mol of sugar in solution because it is soluble but does not dissociate....
