The objects around us are made up of matter, which exists in three forms, namely elements, compounds, and mixtures. It is difficult for many science students to understand the difference between compounds and mixtures, so here we have made it simple for you.
What is a compound?
A compound is formed by combining two or more components chemically and in a certain ratio. A compound refers to a pure form consisting of two or more substances formed by chemical combinations. The difference between compounds and mixtures can be seen from the fact that compounds are generally homogeneous.
When two or more atoms of different elements join together, the resulting bond is a compound. Substances that are chemically formed in a mixture of different elements in a definite proportion are called compounds. Compounds are completely new substances and their properties are different from those of their constituent substances.
A compound is a combination of different elements, so the atoms in the elements are bound together by a chemical bond that cannot be easily separated.
Therefore, there are different types of bonds:
Covalent Bond: A chemical bond in which a pair of electrons is transferred between atoms is called a molecular bond or covalent bond.
Ionic Bond: A chemical bond in which the entire transmission of valence electrons between atoms is called an ionic bond.
Metallic Bond: A bond formed as a result of electrostatic attraction between metal ions and conductive electrons.
What is the mixture?
A mixture is formed when two or more substances combine physically in indefinite proportions. Mixture refers to an impure substance consisting of several physically mixed substances. In addition, the mixture can be varied or homogeneous. In addition, the ratio of the substances contained in the mixture is not fixed, so it can vary.
We can see many mixtures of air, rocks, lakes, and atmosphere all around us. No chemical reaction takes place in the mixture.
Mixtures contain a wide range of two types of substances:
Homogeneous mixture: It is a homogeneous mixture in which the components cannot be easily identified by simple observation.
Heterogeneous mixtures: A mixture of components of different sizes, shapes, or states that can be easily identified by simple observation.
What is the difference between compound and mixture? (Differentiate between compound and mixture)
On the basis of Meaning: –
Compound: – A compound is a pure form consisting of two or more components in a chemical compound.
Mixture: – A mixture is an impure substance consisting of two or more substances that are physically mixed.
On the basis of composition: –
Compound: – The presence of elements in a compound in a certain amount
Mixture: – The presence of substances in a mixture is not a definite quantity
On the basis of types: –
Compound: – Compounds can be of three types: covalent compounds, metallic compounds, and ionic compounds. Compounds can also be classified as organic compounds or inorganic compounds based on the presence of carbon in it.
Mixture: – Mainly two types of mixtures, homogeneous and heterogeneous mixtures.
On the basis of the formula: –
Compound: – A compound definitely has a specific formula based on its constituents
Mixture: – Mixtures are those which have no chemical formula
On the basis of properties: –
Compound: – The characteristics of a particular type of compound are determined and do not differ from each other.
Mixture: – The properties of the mixtures vary depending on the existing materials.
On the basis of substances: –
Compound: – As the properties of different elements combine, new substances are always formed in a compound.
Mixture: – Mixtures do not create new substances because the properties of their components do not change.
On the basis of separation: –
Compound: – It is not easy to separate the components of a compound by physical methods.
Mixture: – It is certainly easy to separate the substances in the mixture by various physical methods such as chromatography, evaporation, and purification.
On the basis of change of temperature: –
Compound: – The change in temperature occurs during the formation of a particular compound
Mixture: – When mixtures are formed they do not undergo any thermal changes.
On the basis of melting point or boiling point: –
Compound: – The compounds have a constant melting point or boiling point
Mixture: – A mixture without a fixed melting point or boiling point
On the basis of examples: –
Compound: – Calcium Carbonate, Methane, Potassium Tartrate, and baking soda
Mixture: – Such as Oil and water, Sugar and water, Crude oil, Air, Gunpowder
