15 Must Read Difference Between Compound and Mixture

What is the difference between compound and mixture?

All physical objects are made of matter which occupies space and has weight. These objects are classified as elements, compounds, and mixtures.

The lesson provides a detailed insight into the difference between compound and mixture in tabular form. Take time to read through for easier revision.

Difference Between Compound and Mixture

What Is A Compound?

A compound is when two or more atoms from different elements combined chemically to form a bond. The resulting compound tends to have different properties from the atoms.

Some of the common bonds that help to bind atoms of different elements together are molecular, atomic, covalent, acids, cation, anions and binary bonds.

Examples of compounds are water (H2O), ethanol (C2H5OH), sodium chloride (NaCl), and potassium chloride (KCL) among many others.

What Is A Mixture?

A mixture is when two or more substances are mixed together in a ratio such that no chemical reaction is likely to take place.

Each component in a mixture tends to retain its properties. The combination of mixtures can easily be separated through certain physical means such as decantation and distillation.

A mixture can either be homogeneous or heterogeneous. A homogenous mixture is the one where a true solution is formed such sugar and water while the heterogeneous mixture is the one where components are not evenly distributed like kerosene and water.

A mixture can also be grouped as solutions, suspensions, and colloids. This classification helps to define the appropriate method of separation.

Core Between Compound and Mixture

  1. Compounds occur when components are chemically bonded whereas components in the mixture are not bonded.
  2. Separation of compounds can be done through electrolysis while mixtures can be done by use of physical means.
  3. The ratio of components in compounds is fixed while the ratio of components in mixtures is variable.
  4. Compounds can either be atomic, molecular, or ironic while mixtures are either homogeneous or heterogeneous.
  5. A compound can be created through a chemical reaction while a mixture through mechanical means.
  6. Components in a compound do not retain their properties while in the mixture they do retain their properties.
