Solutions that show "Tyndall effect":

Milk

Starch Solution

6. Classification:

Elements: Sodium, Tin, Silicon, Silver

Compounds: Calcium carbonate, Methane, Carbon dioxide,

Mixtures: Blood, Air, Soap, Soil, Coal, Sugar Solution

7. Substance: It is a particular kind of matter with uniform properties.

Tyndall effect: It is the scattering of light that is caused when white light is passed through a solution. True solutions (Colloidal particles of the size 1 nm to 1000 nm) Show Tyndall effect

8. Element: It consists of only one type of atoms in its whole constituent. Substances: They can be elements but they can also be molecules. Molecules may contain several different elements. Substances, loosely defined as the word is, could also be compounds, which can include different kinds of molecules.

9. Solute: It is a constituent of a solution that is in less concentration

Solvent: It is a constituent of a solution that dissolves the solute and is in greater concentration in the solution

Solution: It is the mixture of both solute and solvent

HOMOGENEOUS MIXTURE:

• It has the same uniform appearance and composition throughout.
• These are called as solutions
• The particles appear smaller in size
• These are also called pure substances

HETEROGENEOUS MIXTURE:

• These are called as suspensions/colloids
• These substances are not distributed evenly
• The particles are either smaller or larger in size
• These are called mixtures
