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
4. 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
5. Example: soot and dust suspended in the air
Example: water and oil
SOOT POLLUTION
WATER AND OIL
6. 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.
7. 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.
8. – 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
9. – 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
10. – 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)
11. – making of dough into bread.
– gelatin, jelly and whipped cream.
– hair spray
– pen ink
– paints, dyestuff, paper and lubricant
