Classification of mixture
- Mixture composition can vary from one sample to next (Soil, air, ..)
- 1) homogenous mixture = composition doesn't vary within the sample
- Ex: solution (sugar water)
- Solvent (water)
- Solute (sugar)
- 2) Heterogenous mixture = composition may vary within a sample
- ex: trail mix
-
Tincture
- is a solution in which the solvent is alcohol
- Ex: tincture of Iodine
-
How can homogenous mixture be separated?
- 1) Distillation is the process of heating a liquid until it boils, then condensing and collecting the resultant hot vapors
- 2) Chromatography
- separation of mixture that rely on the differential affinities of substances for medium through which they pass, such as paper, gelatin, or magnesia.
-
Emulsion
Liquid dispersed in another liquid in which it's no soluble
-
Solubility
is the ability of solute to dissolve in a solvent
-
Emulsifiers
- substances that maintain the emulsified state, stabilize emulsions
- egg stabilize oil suspended in vinegar => mayo
