HOMOGENEOUS HETEROGENEOUSELEMENTS COMPOUNDS
Solution Suspension
Colloids
CLASSIFIED INTO:
Two-phase mixture, solid is dispersed or spread in solid, liquid and gas.
A heterogeneous mixture, components can be distinguished from each
other.
It is composed of two substances:
– the solute in a solution
– solvent in a solution
 Dispersed material (suspension) are larger than the solute in the solution,
and they are distributed in dispersion medium.
Dispersed materials when mixed with dispersion medium makes the
suspension turbid.
When left alone the dispersed materials becomes visible and settle at the
bottom (container).
Example:
1. Flour in water
2. Fine pepper in a glass of water
3. Mud in the road
Example: cake (mixture of flour, sugar and other ingredients), dirt and
soil, rice and corn.
Example: sand and water, sawdust (lighter particle of sand floating in
water), chocolate granules sink at the bottom of the glass of
water
Example: soot and dust suspended in the air
Example: water and oil
SOOT POLLUTION
WATER AND OIL
like baking.
such as minute maid (with pulp and bits).
(such as water and sand) in the process of purifying water.
– liquid suspension for the kids.
 Homogeneous mixture that sometimes appears as heterogeneous mixture.
 A mixture of:
1. Dispersed phase – solute in the solution. It can be solid, liquid, or gas. The
size of the substance is in between those in solution and a suspension.
2. Dispersion medium – solvent in the solution. It can also be solid, liquid, or
gas.
– dispersed phase and dispersed medium are both solid.
Example: gemstones, pearls, and colored glasses
– result from dispersing liquids in a solid medium.
Example: jelly, jam, cheese, butter, and gelatin
– dispersed phase is a gas and the dispersion medium is solid.
Example: rubber bands, pumice, Styrofoam
GELATIN
PUMICE ROCK
– solids are dispersed in liquid medium.
Example: paint, milk of magnesia, and muddy water
– formed when both the dispersed phase and dispersion
medium are liquids.
Example: milk, hair cream, mayonnaise,
– when gas dispersed in a liquid medium
Example: froth, soap lather, whipped cream
Milk of magnesia
Froth
Soap lather
– colloids of gas. There are solid and liquid aerosols.
Example: 1. smoke (fine solid particles dispersed in gas);
2. fog (liquid substances dispersed in gas );
3. soot and dispersed dust (solid aerosols);
4. insecticides and hair spray mists ( liquid aerosols); and
5. clouds (tiny water droplets dispersed in air)
– making of dough into bread.
– gelatin, jelly and whipped cream.
– hair spray
– pen ink
– paints, dyestuff, paper and lubricant

  • 1. HOMOGENEOUS HETEROGENEOUSELEMENTS COMPOUNDS Solution Suspension Colloids CLASSIFIED INTO:
  • 2. Two-phase mixture, solid is dispersed or spread in solid, liquid and gas. A heterogeneous mixture, components can be distinguished from each other. It is composed of two substances: – the solute in a solution – solvent in a solution  Dispersed material (suspension) are larger than the solute in the solution, and they are distributed in dispersion medium.
  • 3. Dispersed materials when mixed with dispersion medium makes the suspension turbid. When left alone the dispersed materials becomes visible and settle at the bottom (container). Example: 1. Flour in water 2. Fine pepper in a glass of water 3. Mud in the road
