solution (2) chemical Colligative properties of solutions depend on the (1) number of solute particles in nature of the solute (3) concentration of the solvent (4) polarity of the solute particles (1) molarity (2) vapor pressure 2. Adding solute to a solution increases each of the following except (4) osmotic pressure (3) boling point 3. Which response lists all the following pairs that are miscible (mixable) liquids? Par #1 : octane (CsH18) and water Pair #2: acetic acid (CH3COOH) and water Pair #3: octane (C8H18) and carbon tetrachloride(CCU) 4. Bromine, Brzi0, is more soluble in dichloromethane, CH.Clal0, than in water because (1) bromine is polar and dichloromethane has a large number of hydrogen bonds. (2) the intermolecular forces are similar in both bromine and dichloromethane (3) both bromine and dichloromethane have strong ion-dipole interactions(4 the dipole-dipole forces in dichloromethane are much stronger than the dispersion forces in bromine 5. A solution is sitting undisturbed on a side shelf in the laboratory. A small crystal of the same solute of which the solution is made was gently dropped into the solution. Suddenly, a mass of crystals forms and settles to the bottom of the container. The solution is, or must have been (3) supersaturated (4) saturated. (1) dilute (2) concentrated 6. For which case would AHsoln be expected to be negative? (1) if solute-solute interactions are much greater than solvent-solvent and solute-solvent interactions (2) if solute-solvent interactions are the same solvent-solvent and solute-solute interactions (3) if solvent-solvent interactions are much greater than solute-solvent and solute-solute interactions (4) if solute-solvent interactions are much greater than solvent-solvent and solute-solute interactions
