Suspension is a mixture in which particles can be seen and easily separated by settling or filtration.
Solution - is a well-mixed mixture.
Unlike a suspension, a solution has the same properties throughout. Solutions and suspensions also differ in the size of their particles and the way the parts of the mixtures can be separated. Dissolved particles are much smaller than suspended particles.
Solvents and Solutes
All solutions have at least two parts: the solvent and one or more solutes. The solvent is the part of a solution present in the largest amount. It dissolves the other substances. A substance that is present in a solution in a smaller amount and dissolved by the solvent is a solute.
Solutions without water
You don't need a liquid solvent to make solutions. A solution be made of combinations of gases, liquids, or solids.
Particles in a Solution
Whenever a solution forms, particles of the solute leave each other and become surrounded by particles of the solvent.
A colloid is a mixture with small undissolved particles that do not settle out.
Solutions and colloids differ in the size of their particles and how they affect the path of light. Unlike a solution, a colloid contains particles large enough to scatter a light beam.
Lower freezing point
Solutes lower the freezing point of a solvent.
Higher boiling point
Solutes raise the boiling point of a solvent.
