A mixture is a substance which is made up of two or more elements Mixtures or compounds which are chemically not combined together.
Example: – Air is a mixture of gases like oxygen, nitrogen, water vapor, carbon dioxide, etc. The various gases of the air are not chemically combined with one another.
All the solutions are mixtures. The various substances present in a mixture are known as the constituents of the mixture or the components of the mixture.
Mixtures are usually of two types – homogeneous mixture and the heterogeneous mixture.
Heterogeneous Mixture
A heterogeneous mixture does not have a uniform composition throughout the mass. It has visible boundaries of separation between constituents. In other words, those mixtures in which substances remain separate and one substance is spread throughout the other substances as small particles, droplets or bubbles.
Example: – Oil and water mixture, soda water, lemonade, vinegar, brass, kerosene, copper sulphate solution, alcohol.
