A saturated solution is one in which any additional solute added to the solution is no longer dissolved. Solutions are combinations of solvents – most commonly liquids - and solutes, which are typically solids.
Each given solution has a point at which any more solute added does not dissolve. A prime example of this is demonstrated by adding sugar or salt to a glass of water. There is a point when any more of the solid added to the liquid results in the solid remaining in the bottom of the glass. This is, however, dependent upon temperature; most solutions show an increased saturation point in response to increased heat for a given pressure. In the most basic terms, an increase in heat results in more solute dissolving within the solvent.
Solutes are also commonly gases, as with the oxygen in water. Even with water, there is a point at which no more oxygen is dissolved. This is when the additional oxygen introduced into the solution is released as bubbles. Most gas solutions respond to heat and pressure in the same manner as solids, with warmer air absorbing more water vapor than cooler air, as is the case in one common example.Learn More
Air is a homogeneous mixture. In a homogeneous mixture, all of the components are uniformly distributed. This type of mixture contains only one phase of matter: gas, liquid or solid.Full Answer >

Saline solutions are sterile solutions of salt and water that are easy to create. To make a saline solution, place 1 cup of water and 1/2 teaspoon of table salt into a sauce pot. Boil the water for 15 minutes, and allow it to cool completely before storing the solution in a sterile jar.Full Answer >
Suspension is when particles of solid material are held within a fluid. The particles are large enough to not dissolve in the fluid, and they separate easily when disturbed. Particles may settle to the bottom of the container when left undisturbed.Full Answer >
