Question

what is homogeneous and heterogeneous mixture​

Answer 1

Answer:

Homogeneous Mixture:

In chemistry, a mixture is a material made up of two or more different substances which are physically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids. 

Heterogeneous Mixture:

A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts.

1. Homogeneous Mixture: It is a mixture in which the constituents are uniformly distributed and each part of the mixture has the same properties.

For example, salt dissolves in water to form a homogeneous mixture. Particles of salt and water are uniformly distributed and each part of the mixture has the same properties. Some other examples of homogeneous mixture are sugar and water solution, air (mixture of gases like nitrogen, oxygen and carbon dioxide), etc.

2. Heterogeneous mixture: It is a mixture in which the constituents do not get mixed uniformly and each part of the mixture has different properties.

For example, sand and sawdust form a heterogeneous mixture. Each part of the mixture has different properties. Some other examples of heterogeneous mixture are water and oil, chalk in water, pond water, soil, etc.

The substances (components) present in the mixture do not lose their identity. These components can usually be separated by simple physical methods.

For example, common salt that is used in our kitchen is from sea water.
