Difference between Homogeneous mixture and Heterogeneous mixture

Mixture is the combination of two or more pure substances where each substance retains its own identity. It is collection of dissimilar particles that will not undergo a chemical reaction.

A mixture has variable combinations
Example: alcohol-water mixture, both co-exist together.

A mixture can be either homogeneous or heterogeneous
 

 Homogeneous Mixture vs Heterogeneous Mixture

Homogeneous mixture

1. It has uniform composition

2. The particles are uniformly distributed

Example of Homogeneous mixture: alcohol-water mixture we call this homogeneous mixture as a solution, Sugar and water, Air is a homogeneous mixture of gases

Heterogeneous mixture

1. It has a non-uniform composition

2. Particles involved are not uniformly distributed

Example of Heterogeneous mixture: sea water, concrete, a mixture of salt water and sand.
