Part A: Solution Properties 10 points

List five of the six properties of a true solution:

1. It is homogeneous mixture of two or more components, solute and solvent

2. It has variable composition, that is, the ratio of solute and solvent may be varied.

3. The dissolved solute is molecular or ionic in size

4. It may be colored or colorless but it is usually transparent

5. The solute remains uniformly distributed throughout the solution and will not settle out with time (every drop has exactly the same concentration)

6. The solute generally can be separated from the solvent by purely physical means (for example evaporation or distillation)
