Classification of Matter
Matter – anything that has mass and takes up
space
Pure Substance - matter that CANNOT be
physically separated
Compound – made up of TWO or MORE elements
Element – matter made of only ONE kind of
atom
Mixture – matter that CAN be physically separated
and contains TWO OR MORE substances
Homogeneous (solution) – uniform
composition or substances evenly mixed
Heterogeneous – substance not evenly mixed
Colloid – particles do not settle
Suspension – particles do settle, particles are
spread out but do not dissolve

Solution = mixture that dissolves and is spread out evenly
2 PARTS OF A SOLUTION
Solute – the part that dissolves
Solvent – the substance that dissolves the solute (the
larger part of the solution)
example of a solution:
salt water
the salt is the solute
the water is the solvent (water is sometimes called the
universal solvent)
Types of solutions
Liquid solutions ex: vinegar
pop (CO2 gas in the liquid)
*cold pop holds more CO than warm pop
Gaseous solutions ex: air (oxygen dissolved in nitrogen)
Solid solutions ex: bronze (copper and tin)
brass (copper and zinc)
steel (iron and carbon)

Solubility – the ability of a substance to dissolve in
another substance.
Hot tea will dissolve more sugar than cold tea.
Cold soda will dissolve more carbon dioxide gas than warm soda.
Soluble – when one substance (solute) is
dissolved by another substance (solvent)
“like dissolves like”
example: salt is soluble in water
Insoluble – when one substance does NOT
dissolve in another
example: oil is insoluble in water
