Is air a homogeneous mixture?

Air is a homogeneous mixture. In a homogeneous mixture, all of the components are uniformly distributed. This type of mixture contains only one phase of matter: gas, liquid or solid.

Other examples of homogeneous mixtures include sugar water, rain water, vodka, vinegar, dishwashing detergent and steel. In homogeneous mixtures, the individual components cannot be separated or visualized easily, and all samples of the mixture are the same.

A heterogeneous mixture is the opposite. In this type of mixture, the components are not uniformly distributed. The components can have different properties and differing characteristics. In a heterogeneous mixture, there are at least two or more phases of matter.
