How are mixtures classified?

Mixtures can be classified into two main categories: homogeneous and heterogeneous. A homogeneous mixture is one in which the composition of its constituents are uniformly mixed throughout. A heterogeneous mixture is a nonuniform mixture in which the components separate and the composition varies.

Is Salt a mixture?

Ordinary table salt is called sodium chloride. It is considered a substance because it has a uniform and definite composition. Salt easily dissolves in water, but salt water cannot be classified as a substance because its composition can vary.

What are the 2 types of mixtures answer?

There are two kinds of mixtures : heterogeneous and homogeneous. In heterogeneous mixtures , two or more ingredients (or phases, regions with uniform composition and properties) intermingle, but remain physically separate. Often it is possible to separate the original ingredients by physical means, such as filtering.

What are two examples of mixtures?

Is water a mixture?

2 Answers. A mixture is when two or more substances combine physically together. However, in water , two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone. Therefore, water is not a mixture ; it is a compound and it is pure.
