In chemistry, a mixture It is the combination of two or more pure substances that come together without changing chemically. For this reason, it is possible to separate the components of the mixtures by certain physical procedures, such as filtration wave distillation.

In general, mixtures are classified into homogeneous and heterogeneous. Sometimes a third category is distinguished with intermediate characteristics: that of colloids.Mixes are found practically everywhere; many of the objects around us include mixtures, both homogeneous and heterogeneous:

• Homogeneous mixtures: Are those that appear as totally uniforms, without discontinuities even at ultramicroscope, so they are said to have a single phase. The substances that make up a homogeneous mixture are evenly distributed. Solutions are typically homogeneous mixtures, and there are liquid, solid and gaseous solutions. Other types of mixtures are suspensions, emulsions, foams, gels and alloys, the latter so important in the steel industry.

• Heterogeneous Mixtures: They are not uniform. It is possible to observe the discontinuity of its phases (any heterogeneous mixture has at least two phases) to the naked eye, although sometimes it must have an element of greater resolution than the human eye to appreciate and distinguish them. Heterogeneous mixtures are often obtained when trying to bring together substances that are insoluble or immiscible. This makes the components separate and form different phases. Because of this non-uniform distribution, samples from different parts of a heterogeneous mixture can have different compositions.
