Solutions

Permanent blend of two or more readily mixed substances

2

Solute

Substances being dissolved by the solvant

3

Dilute

Solvent > Solute

4

Concentrated

Solvent >_ Solute

5

Saturated

Solute > Solvent

6

Suspension

Blend of two or more
Immisable substances that separates upon standing

7

Colloids

Powders- blend of 2 or more immisable substances whereby a substance is finely ground into small particles

8

Emulsions

2 or more immisable(not readily mixed) substances that create a permanent blend with the aid of a binder, emulsifier, or gum.

9

Oil in water Emulsion

Water base product (more water) suspended in H20 with small oil particles

Lighter, penetrate, milky lotion, non occlusive.

10

11

5 physical (properties) chemists can tell the differences

1. Density
2. Specific gravity
3. Taste
4. Odor
5. Color

12

Chemical (properties) chemists can tell the difference

Combustibility
Ability to support combustibility

13

Physical change

Changes physical form but not chemistry.

Ex
Freeze water- ice
Heat water- steam

14

Chemical change

Changes the chemical structure/nature

Acid Base- reaction
Oxidation- reduction
Oxygen creates change

15

Acidity PH

0-6.5

16

Alkalinity PH

7.5-14
