Question

Differentiate between homogeneous and heterogeneous mixtures with examples.

Answer 1

A homogeneous mixture is a mixture having a uniform composition throughout the mixture. For example, mixtures of salt in water, sugar in water, copper sulphate in water, iodine in alcohol, alloy, and air have uniform compositions throughout the mixtures.

On the other hand, a heterogeneous mixture is a mixture having a non-uniform composition throughout the mixture. For example, composition of mixtures of sodium chloride and iron fillings, salt and sulphur, oil and water, chalk powder in water, wheat flour in water, milk and water are not uniform throughout the mixtures.

Answer 2

	homogeneous mixtures	heterogeneous mixtures
1.	Made up of regular materials, it has a uniform composition.	Made up of more than one different material it does not have a uniform composition.
2.	It has an absence of separation boundaries between different materials.	It has clear separation boundaries between different materials.
3.	Its components are not easily seen.	Its components can be seen.
4.	Example: Salt in water	Example: Oil in water
