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
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.
