Mixture or Compound many think the same about these two! But here are some major differences between compound and mixture that will clear some confusion.

The mixture comprises two or more mixed substances, but neither chemically nor in an inaccurate amount, while the compound contains two or more chemically integrated elements and a fixed ratio.


The substance created chemically in a fixed ratio as a mixture of different elements is called compounds. Compounds are completely different substances, the properties of which vary from those of their constituent substances. differences between compound and mixture The compound is the fusion of different elements such that the chemical bond binds together the atoms contained in the elements which cannot be easily broken. Bonds are formed from the sharing of electrons among atoms. 

Types Of Compound

Water (H2O), ethanol (C2H5OH), sodium chloride (NaCl), for example, are some of the typical compounds, made up of unique proportions of their constituents, which often have a chemical identity.

Molecular, acids, cations, anions, and binary bonds are the various bond forms. Many of these have distinct chemical identities and formulas. So, there are various forms of bonds:

1. Covalent bond

A chemical bond in which a pair of electrons are exchanged between atoms is referred to as a molecular bond or a covalent bond.

2. Ionic bond

A chemical bond in which the entire single exchange of valence electrons takes place between atoms is called the ionic bond.

3. Metallic bond 

It is a bond between metallic ions and conduction electrons that occurs as a result of electrostatic attraction.


Mixtures, including air, rocks, seas, and even the atmosphere, are all around us. Some have physical properties combined with the components and not with any chemical properties and not even in a defined ratio. differences between compound and mixture Therefore, we may assume that mixture formation takes place by the combining of two or more substances, but not in a defined proportion. This gives a brief introduction on the characteristics, now let’s find some differences between compound and mixture.

Types Of Mixture

In mixtures, the chemical reaction does not occur, the fusion takes place physically. So, mixtures include atoms or molecules of two or three different forms, or at least one atom and one molecule.

No fixed melting or boiling point is required for mixtures. Via physical techniques such as filtration, decantation, distillation, mixtures can be isolated. Mixtures may either be heterogeneous or homogeneous.

1. Homogeneous

These are called true solutions, as the constituents present in this type are spread all over evenly or similarly. Sugar solution, alcohol, and water mixing are some of the examples.

2. Heterogeneous

If the constituents in the mixture are not uniformly distributed, they are classified as heterogeneous mixtures. For example, (oil + water), a sulfur and iron mixture, gravel, etc.

In addition to the two above, the mixtures are further categorized on the basis of the type of particle size present there. They are solutions, suspensions, and colloids.

3. Solutions

They contain nano-sized particles that are less than 1nm in diameter. The solution cannot be isolated by the process of decantation or centrifuge. Examples include dissolved oxygen in water, air, and gelatin.

4. Suspensions

The particles are so small in this solution that they are not visible by naked eyes and the particle size ranges from 1nm to 1mm.

The colloid solution shows the effect of Tyndall, and the decantation and centrifugation process will isolate the colloidal constituents. A few examples are blood, smoke, cream.

5. Colloids

These are kind of heterogeneous in nature, showing the influence of Tyndall, too. The particles within it are sufficiently large and can be separated by centrifugation or decantation. A few examples are clay, granite, dust, or air contaminants.

Differences Between Compound and Mixture

For example, Seawater, Crude Oil, Mineral Oils, Alloys (Brass, Bronze) are some of the mixtures while, Water (H2O), Hydrogen Peroxide (H2O2), Sodium Chloride (NaCl), Baking Soda (NaHCO3), etc. are some of the compounds.  differences between compound and mixture Anything that occupies space has mass and volume, as per the theory of classical physics, which is known as matter. It is also possible to categorize matter into two groups, mixtures, and pure substances.

Elements and compounds are made up of pure substances. We have taken the liberty to break down the differences between compound and mixture with this in mind. Have a look: 

Particulars  Compound  Mixture


Compounds are substances that can be formed by combining two or more elements chemically. Mixtures are impure substances that are made of two or more substances that are physically mixed.


Homogeneous in nature Either homogeneous or heterogeneous in nature.


Water, salt, baking soda, etc. Oil and water, sand and water, smog (smoke + fog), etc.


There are three kinds of compounds: covalent compounds, metallic compounds, and ionic compounds. Mixtures are primarily of two types, namely homogeneous and heterogeneous mixtures.


The elements are present in a fixed quantity, which implies that their ratio is fixed. The substances present in the mixtures are not in fixed amounts, which means that their ratio varies.


Depending on the constituents present, compounds have a particular formula. Mixtures do not have a certain formula.

Melting/Boiling point 

There is a fixed melting and boiling point for the compound. There is not a fixed melting or boiling point for mixtures.

Heat change 

There are a heat shift and the absorption or release of energy during the creation of the compounds since it is a chemical reaction. No heat shift or energy presence occurs when creating a mixture.



It is not easy to separate the elements and, if achieved, it is by chemical methods. By distinct physical methods such as filtration, chromatography, evaporation, the substances of the mixtures are simple to separate.


The properties are set for the specific compound type and do not differ, as the elements contained in the compounds are fixed and are in the fixed ratio. The properties of the mixtures do differ (not fixed) since it depends on the nature and quantity of substances to be mixed with.


The table consists of all the differences between compound and mixture. The basic material is the elements and more can be divided into easier forms. There are two or three different atoms or elements in the compound; mixtures contain different substances, on the other hand.

In conclusion, compounds are formed with a combination of elements, and mixtures are formed with the combination of substances physically. The major differences between compound and mixture are the chemical reaction in the process and composition.
