Difference between compound and mixture

Difference between compound and mixture: An element is a material composed of a simple type of atom, a compound is a substance formed by two or more elements that combine chemically and a mixture is the combination of substances, the same or not, that can be separated by physical methods.

Two terms that are used frequently in chemistry are compound and mixture, they are similar but different from each other, and their differences will be detailed in the following lines to understand them in a better way. There are many definitions of these two terms that can be confusing, but to explain them in simple words, compounds are substances that have no variable composition, while mixtures consist of variable forms.

The best example of a compound can be water, which is made up of hydrogen and oxygen molecules, the structure of water is similar, and all the particles are properly combined. On the other hand, the best example of mixing will be a perfume consisting of different added substances.

There is no good structure, two different materials can be mixed in any proportion, and they don’t have to be the same. Another example is the ocean, which has a different concentration in various places and is not always equally distributed. There are other ways to explain the difference between the two terms.

Compounds, for example, can be called substances that are made up of two or more elements that have been added with the help of a chemical method, while the mixture can be called an element that has been made up of two or more elements that have been added.

together in a physical way. For compounds, they can have their own properties, but when mixed, they all start to show different but fixed amounts and each one proportion.

On the other hand, for a mixture, when two substances are added together, they do not form a new substance, in fact, various types of materials can be obtained.

Another difference between them is that the mixtures have elements that have been added together and can be separated again with the help of any physical method. While the elements of a compound can also be separated but with the support of a chemical reaction. Below is a brief description of both terms.

Key Differences

  • Compounds are pure substances in every way. The mixture is always an impure substance.
  • Compounds always have a fixed ratio; The mix never has a fixed fee.
  • Compounds are two or more substances that are mixed with the help of a chemical reaction, while the mixture is two or more substances that are mixed with the support of a physical process.
  • The components of a compound can be separated only by chemical reaction; The elements of a mixture can only be separated with a physical action.
  • Compounds have properties that depend on the two elements. The mixture has properties that are variable and depend on some elements.
  • The properties of a compound may or may not be different from its elements; The properties of a mixture are always the same as its elements.

Definition of compound

In simple words, compounds can be defined as two or more elements that are combined with each other. For a more technical definition, the compound can be something that is a combination of two or more elements that are chemically combined with each other.

The components react chemically and form bonds with each other. Compounds are always pure substances that have different properties. They are added in fixed amounts and their properties are similar at all points within themselves. Once they are joined, the original elements no longer have their properties and show new characteristics.

For example, in water, hydrogen, and oxygen, which have different properties, come together and result in new properties that are neither like oxygen nor hydrogen.

If there is a need for the reversible reaction, it is only possible chemically, these cannot be separated with any physical reaction. Another important one in this regard is salt, which is made up of different elements such as sodium chloride, calcium silicate, and potassium iodide.

They are different but they come together to form a salt, if a chemical reaction is carried out on the salt, all these constituents can be obtained again.

A compound is a pure chemical substance made up of a particular set of molecules or ions that are chemically bound together. They may be:

  • molecular compounds linked by covalent bonds;
  • salts linked by ionic bonds;
  • compounds of metal with metal joints; Y
  • complex compounds.

Types of compounds

  • Inorganic compounds : are those compounds in whose composition there are no bonds between carbons. Example: water H 2 O, sulfuric acid H 2 SO 4 , silver nitrate AgNO 3 .
  • Organic compounds : are those compounds where carbon is the base element in the construction of the molecule. Example: ethanol H 3 C-CH 2 OH, proteins and carbohydrates.

Examples of compounds in everyday life

  • Water: Water is a chemical compound formed by the chemical union of two hydrogen atoms and an oxygen atom H 2 O. Water is the most essential compound for the maintenance of life on the face of the Earth.
  • Table salt or sodium chloride: The salt we use in the kitchen is sodium chloride NaCl, which is an ionic compound, that is, between the elements sodium and chlorine, ionic bonds are established, where there is transfer of electrons.
  • Glucose: Glucose, with the formula C 6 H 12 O 6 , is an organic compound made up of carbon, hydrogen and oxygen. It is synthesized in plants by the photosynthesis process and is used by heterotrophic organisms as a source of energy.

Definition of mixture

Mixes are the easiest things to find, they are everywhere. From creating a drink to adding different colors. A mixture can be defined as a combination of two or more elements that come together to form another substance with the help of a physical reaction.

Because it is a physical reaction, the properties of the mixture are similar to those of the added elements. To recover these characteristics, it is necessary to perform a physical process. The substances must be in the proper proportion to obtain the required part.

No new material can be formed in a mixture, the originally added ones retain their properties and are present in different proportions. This is what differentiates them from compounds, they are random processes without fixed methods, from two elements by mixing them differently, separate substances can be obtained.

A mixture is the combination of various elements and / or molecules that are not chemically bound . It differs from pure substances, such as elements and compounds, in that the components can be separated by various physical techniques.

Types of Mixtures

  • Homogeneous mixture: it is one whose composition is uniform and each part has the same properties. For example the mixture of water and vinegar, the mixture of alcohol and water.
  • Heterogeneous mixture: it is one in whose composition the parts of the mixture can be distinguished. For example: the mixture of oil and vinegar, the mixture of a fruit juice.

Examples of mixtures in everyday life

  • Air: Air is a mixture of 78% nitrogen, 21% oxygen, and the remaining 1% is represented by argon, water vapor, and carbon dioxide.
  • Sea water: Seawater is a mixture of water, ions, salts, and a variety of other molecules.
  • Mayonnaise: Mayonnaise is a mixture of fat, protein and water emulsion. To prepare mayonnaise you have to beat the egg with oil and salt in a certain proportion.

Conclution

There are many terms that can give the impression that they have the same meaning, but in reality, they are very different from each other, compound and mixture are these terms that have been explained in this article and the concepts have been clarified for people who do not have it. I generally know a lot about them.
