Which of the following statements about colligative properties of solutions is FALSE?
1. The higher the concentration of solute in the solution, the lower the vapor pressure of the solvent.
2. Colligative properties are identical for all solvents
3. Colligative properties arise from the con- centration of the solute but not the inter- molecular forces of the solute
4. Osmosis is a colligative property. 5. Colligative properties assume ideal solutions
