The Definition of Solutions:

(Solutions)
- Are made up of more than one substance.
- Solutions CANNOT be separated by
mechanical means such as sorting, filtering, settling, or spinning.
- This is commonly called a mechanical mixture.

1

The Definition of Heterogeneous Mixture or Mechanical Mixture:

A mixture with two or more visible components or phases. They CAN be separated by mechanical means such as sorting, filtering, settling, or spinning. This is commonly called a mechanical mixture.

2

(2nd definition of Solutions)

Definition of Homogeneous Mixture:

A mixture will with one phase or visible component. It CANNOT be separated by mechanical means since the particle is in solution - dissolved and too small to separate this is commonly called a solution.

3

Definition of Dissolve:

Able to form solution.

4

Definition of Solute:

The substance that is dissolved.
There is usually less of this substance.

5

Definition of Solvent:

The substance that does the dissolving.
There is usually more of this substance than the solute.

6

Definition of Residue:

The solute that remains after the solvent is evaporated.

7

Definition of Evaporation:

The process of boiling off the solvent (the liquid) from the solute (residue) in a solution.

8

Definition of Distillation:

A process whereby the solvent and solute are separated by the process of boiling and condensation.

9

Definition of Dilute Solution:

A solution that contains a small amount of solute compared to the amount of solvent.

10

Definition of Concentrated Solution:

A solution that contains a large amount of solute compared to the amount of solvent.

11

Definition of Saturated Solution:

A solution that can dissolve more solute.

12

Definition of Unsaturated Solution:

A solution in which no more solute will dissolve.

13

Definition of Crystal:

A solid with a defined angular shape.

14

Definition of Aqueous Solution:

A process whereby oxygen is forced through water.

15

Definition of Coagulation:

A process whereby small particles gather together.

16

Definition of Sedimentation:

A process used to separate small insoluble particles from the water by allowing the particles to settle down in undisturbed water.

17

Definition of Filtration:

The process whereby an insoluble substance is removed from a liquid by pouring it through a fine screen.
- coffee filters are an example.
- you can also use layers of sand and gravel, which you find most often in poor filters.

18

Definition of Disinfection:

The process whereby chlorine or other chemicals are added to kill harmful bacteria before the water is distributed to the consumers.
