Mixtures in which their components or ingredient are not distinguished from one anothet.
homogeneous Mixture
Main component in heterogeneous mixture .
Solvent
The dissolved additive in heterogeneous mixture.
Solute
It is considered as the universal solvent.
Water
It can determined by the amount of solute that can be dissolved in a fixed amount of solvent.
Solubility
Which of the following is not soluble in water?
a. moth ball
b. salt
c. sugar
d. vinegar
a. moth ball

In solution, the additives is called______, while the substance that dissolves the first is called the_____.
a. solute, solvent
b. solvent, solute
c. seasoning, watet
d. solubility, concentration
a. solute , solvent
Solubility is measured in terms of ______.
a. how much solute is actually dissolved in the solvent
b. how much solvent is actually dissolved in the house
c. how much solute can be dissolved in a fixed amount of solvent .
d. how much solvent can be dissolved in a fixed amount of solute.
c how much solute is actually dissolved in a fixed amount of solvent
The particles of the dispersed ingredients are not really dissolved oin the liquid. They just settle at the bottom.
Suspension
The dispersed particles do not settle because they are light enough to stay dispersed in the dispersal medium.
Colloids
Immiscible liquid forced into a consistent mix.
Emulsion
Gas-in-liquid Colloids
Foam
Solid mixed with liquid colloids
Gel
Solids or liquids dispersed in has colloids.
Aerosol
What are the different ways to separate heterogeneous mixtures?
- using fan and wind
- using machines
- panning
- sparation of immiscible liquids
- by strainets
- using magnet
Separating solid mixture by letting wind blow away lighter components of the mixture.
Winnowing
Separating immiscible liquids by scooping or pouring out the layers of each liquid.
Decanting
Mixtures with metal components can be separated by_______.
Magnet
