Solutions

A solution is a mixture of two or more substances, where one substance is completely dissolved in the other. 

Solute is the material that gets dissolved.  (i.e. - The Kool-Aid powder is the solute when you make Kool-Aid.)

Solvent is the material that dissolves the solute.  (i.e. - The water is the solute when you make Kool-Aid.)

The solute particles in a solution are evenly spread out in the solvent - so solutions are always clear (except for solid solutions, like bronze). 

Dissolving is when the solute particles spread evenly throughout the solvent.

 

Solutions are made up of two or more substances - but they appear to be only one substance.

One way to test whether a mixture is a solution is by shining a beam of light through it.  If you can't see the beam of light, then you have a true solution.  If the particles in the solution cause the beam to be visible, then you do not have a true solution.  This is called the Tyndall Effect.

Concentration has to do with the amount of solute in a certain amount of solvent.  More solute raises the concnetration and makes the solution concentrated.  Less solute lowers the concentration and makes the solution dilute.  You can also dilute a solution by adding more solvent.
