Question

Differentiate between homogeneous and heterogeneous mixtures. Give examples.
​

Answer 1

Answer:

$\large\mathsf{\red{\underline{\underline{Homogeneous~ mixture}}}}$

• Mixtures in which the particles of the substances present cannot be seen.
• It has a uniform composition.
• It has only one phase.
• It can’t be separated out physically.
• ‘homo’ means the same.

Example:

1. A mixture of alcohol and water.
2. Solution of sugar and salt in water.
3. Cold drinks and syrups and air (pure).

$\large\mathsf{\red{\underline{\underline{Heterogeneous~ mixture:-}}}}$

• Mixtures in which the particles of the substances can be seen easily.
• It has a non-uniform composition.
• There are two or more phases.
• It can be separated out physically.
• ‘hetero’ means different.

Example:

1. A mixture of sodium chloride and sand.
2. Chalk in water
3. Sand and iron filings or sulpher and iron filings
