Classify each of the following as a homogeneous or heterogeneous mixture. Give reasons.

Soda water, wood, air, soil, vinegar, filtered tea.

(i) Soda Water: Homogeneous Solution

the soda water contains carbon dioxide (CO₂) and water that is perfectly dissolved under pressure.

(ii) Wood: Heterogeneous Mixture

Since the composition of wood varies from plant to plant thus wood is a heterogeneous mixture.

(iii) Air: Heterogeneous Mixture

Air contains various other gases mixed with it such as oxygen, nitrogen etc. due to this air is heterogeneous.

(iv) Soil: Heterogeneous Mixture

Example: Soil consists of various matters, sand, pebbles etc that makes it a heterogeneous mixture.

(v) Vinegar: Homogeneous Mixture

Vinegar is made of acetic acid and water that is mixed perfectly. Due to this vinegar is homogeneous.

(vi) Filtered Tea: Homogeneous Solution

After tea is separated from the tea leaves it is a perfect homogeneous solution.
