Mixtures are formed when two or more substances (elements or compounds) mix together without participating in a chemical change. The substances need not necessarily mix in a definite ratio to form a mixture.

Heterogeneous and Homogeneous Definition

1. What is homogeneous Mixture

Homo means sane. The mixtures in which the components have a uniform distribution throughout the mixture are known as homogeneous mixtures. For example, salt and water is a homogeneous mixture as the taste of the water will be the same if you take a sip from any portion of water. This shows that salt is uniformly distributed in the mixture.

e.g. Salt and water, Sugar and water, Alcohol and water, etc.

2. What is Heterogeneous Mixture

Hetero means different. The mixtures in which the components do not have a uniform distribution throughout the mixture which means in which the components are unevenly distributed are said to be heterogeneous mixtures. For example, sand and water is an example of the heterogeneous mixture as sand does not distribute uniformly in water. e.g. Sand and water, Sugar and salt, Ice in water, etc.

Properties of Heterogeneous Mixture

• All solutions are the instances of a homogeneous mixture.

• The size of the particles in such a case is less than one nanometer.

• They don't demonstrate Tyndall impact.

• You can't separate the boundaries of particles.

• You can't separate the constituent particles here utilizing centrifugation or decantation.

• Alloys are the instances of a solution.

Properties of heterogeneous mixture

• Most of the mixtures are heterogeneous aside from solutions and alloys.

• The constituent particles are not present uniformly here.

• You can distinguish the components effectively.

• Generally, at least two stages are available in a heterogeneous mixture.

• The size of the particles here is in the range of one nanometer to one micrometer.

• They demonstrate the Tyndall impact.

Difference Between Homogeneous and Heterogeneous Mixtures

1. Homogeneous mixtures

• A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution.

• Components of homogeneous mixture cannot be seen through naked eyes.

• In this mixture the component sizes are atomic/molecular level.

• Components of homogeneous mixture cannot be separated easily.

• The constituent particles in a homogeneous mixture possess the same physical properties.

• Example: salt solution, sugar solution, air, etc.

2. Heterogenous mixtures

• A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.

• Components of heterogeneous mixtures can be seen through naked eyes.

• Here, in this mixture, the size of particles are large.

• Components of heterogeneous mixture can be separated easily.

• The constituent particles in heterogeneous mixture possess different physical properties.
