**What is A Solution?**

A solution is a homogeneous mixture or cominbation that holds a solvent and at least one solute. Homogeneous mixtures have the same porportions throughout the given mixture. An example of a homogenous mixture would be sugar water. When you mix the sugar with the water all of the sugar particles are distributed evenly through out the glass. A solution is also a mixutre of two or more substances that can't be seperated by mechanical means, like filtrations. Gases and solids that dissolve in a liquid are said to be soluable. A solvent is the part of the solution present in the larger solutions. It dissolves the other substances! A solute is the substance that is present in a solution in smaller amounts and is dissolved by the solvent. Solutes decrease the freezing point and increase the boiling point of the solvent.media type="custom" key="6118191" align="right"

** Effects on Solutes and Solvents **

Particles of a solute leave each other and become surrounded by particles of the solvent."A solution has the same properties throughout. Most solvents and the solutions form are liquids, but they can be gases or solids. It cointains solute particles (molecules or ions) that are too small to see."(Frank, Little, and Miller 84). In many every day solutions the solvent is water. For example, if you put sugar in water it is the starting solution for flavored soft drinks. But also many solutions are made with solvents other than water. An example gasoline is the solution for many different liquid fuels.

** Colloids and Suspensions **
Unlike a soultion, a suspension doesn't have same exact properties throughout. A suspension contains visible particles that are larger than the particles in solutions. A suspension is a mixture in which particles can be seen.They are easily seperated by settling or filtration. An example is if you stir together pepper and water they never mix completely. When you finish you can still see pepper flakes floating on the waters surface, and at the bottom of the glass. an example of this is distillation.If the solvent of a solution is boiled away, the solute particles are left behind. In distillation, the solvent is boiled away then condensed to a pure liquid which is collected.

A colliod contains larger particles than a solution. Particles are still too small to be seen easily, but are large enough to scatter a beam of light. A colliod is a mixture contaning small undissolved particles. The particles don't settle out. An example of a colliod are the fats and protiens in milk. They from globular particles. They are big enough to scatter light even though they are stilll too small to be seen. Other examples of colliods are gelatin, fog, mayonnaise, shaving cream, and whipped cream (yum).
