HW 10:

Objective 1: Understanding Solutions

1. What are the characteristics of solutions, colloids, and suspensions? Suspensions are a "homogeneous fluid" that has solid particals that are large.  Colloids disperse in a substance evenly and solutions have much smaller particals than either of the other two.

2. What happens to the particles of a solute when a solution forms?  The particals from the solute go away and are a part of the solevent.

3. How do solutes affect the freezing point and boiling point of a solvent?  The boiling point of the solvent gets bigger when a solute is added because a solution has a bigger boiling point compared to a pure solvent. The freezing point gets lower also.

5. What effects do solutes have on a solvent’s freezing and boiling points?  A solute makes the boiling point bigger because a solution has a bigger boiling point compared to a pure solvent. It also makes the freezing point a lot lower.  The coligative property helps to understand the boiling point elevation.
