Mixtures
|
Solution>Saturated Solution / Suspension>Emulsion / Coloid Definition: A material formed by physical combining of two or more materials. Substances keep their own properties.
|
|
Solutions
|
A mixture of one substance, dissolved throught another. All parts of the solution have the same properties such as color, odor and taste
|
|
Solutions-Examples
|
Borax solution, sugar water, instant tea
|
|
Saturated Solutions
|
A solution that is full of the dissolved substance.
|
|
Saturated Solutions-Examples
|
Sugar water, chicken broth, soda/pop
|
|
Solute
|
A substance that becomes dissolved.
|
|
Solute-Examples
|
Sugar, sugars in pop
|
|
Solvent
|
The part of the solution that dissolves the substance.
|
|
Solvent-Examples
|
Water (H2O)
|
|
Alloys
|
Solutions of two or more metals and other solids.

|
|
Dissolving
|
To mix completely with a liquid
|
|
Reaction
|
two or more substances undergoing a chemical change
|
|
Evaporation
|
a change from a liquid/solid to a vapor
|
|
Saturation Point
|
the point at which the solution holds as much as it can.
|
|
Super Saturation
|
A solution holds more of a substance when heated than when normally disolved at cooler temperatures
|
|
Suspension
|
A mixuture made of different parts that will separate with time.
|
|
