Objective 1
1. A solution is a homogeneous mixture of 2 substances. A colloid is a substance evenly dispersed throughout another substance. A suspension is a homogeneous fluid that has solid particles that are too large for sedimentation.
2. When a solution forms, the particles of a solute leave each other and become surrounded by the particles of the solvent.
3. The boiling point of a solvent increases when a solute is added because a solution has a higher boiling point than a pure solvent. The freezing point decreases too.
4. You have made a solution because the particles dissolve.
5. A solute increases the boiling point because a solution has a higher boiling point than a pure solvent. It also lowers the freezing point.
