Question

The sugar solution is a homogeneous mixture whereas oil and water is a heterogeneous mixture. Justify.

Answer 1

Homogeneous mixtures

• A homogeneous mixture is a gaseous, liquid, or solid mixture that has the same proportions of its components throughout a given sample.
• It is uniform in composition throughout.
• There is only one phase of matter observed in homogeneous mixtures.
• Example -Salt solution.

Heterogeneous mixtures.

• In heterogeneous mixtures, particles are distributed non-uniformly
• More than one phase can be seen by the naked eye.
• Non-uniform composition.
• Example- Seawater

The sugar solution is a homogeneous mixture whereas oil and water are a heterogeneous mixture

• The sugar solution is a homogenous mixture because sugar dissolves and spread throughout the glass of water
• It forms a single phase as it is a homogeneous mixture
• In oil and water, they are heterogenous mixtures because oil and water do not mix. It forms two layers.

Hence the sugar solution is a homogeneous mixture whereas oil and water are a heterogeneous mixture.
