Furthermore, all the particles in a solution have the size of a molecule or an ion. Thus, we cannot observe them by the naked eye. Also, the solutions can have a colour if the solvent or the solutes can absorb visible light. However, solutions are typically transparent.
Moreover, these mixtures can occur in a liquid, gaseous or solid state. But, most common solvents are liquids. Also, among liquids, we consider water as a universal solvent, because it can dissolve many substances than any other solvent.
Besides, we can dissolve gas, solid or any other liquid solute in liquid solvents. However, in gas solvents, only gas solutes will dissolve. There is a limit to the amount of solutes that we can add to a certain amount of solvent. When it reaches the maximum limit, the solution becomes saturated. But, if the amount of solute is very low, the solution becomes diluted. If there is a high amount of solutes in the solution, it is a concentrated solution.
By measuring the concentration of a solution, we can get an idea about the amount of solutes in the solution. Compounds are chemical substances containing two or more different chemical elements bonded to each other. Whereas, a solution is a homogeneous mixture of two or more substances. The chemical formula represents one molecule of a substance. When two or more elements react chemically and combine in a fixed ratio the product formed is said to be a compound.
Compounds are represented using a chemical formula that describes the ratio in which the elements have combined to form a compound. Compounds can be molecular compounds or salts. Properties of Compounds are:. Difference between Mixtures and Compounds Lets now understand some major differences between mixtures and compounds as: Compounds Mixtures 1.
Compounds are formed by a chemical reaction between two or more elements. Mixtures are formed by mixing two or more substances physically such that no chemical reaction takes place between the components.
Elements always combine in a fixed ratio by mass to form a compound. The ratio of substances is not fixed and can be variable. There is a change of energy during compound formation. No energy change takes place. Compounds cannot be separated physically but require special chemical techniques to separate the elements.
Mixtures can be separated physically. The elements lose their properties and the compound formed exhibits new physical and chemical properties. The components of a mixture retain their original properties. Compounds may be organic or inorganic. Mixtures may be homogeneous or heterogeneous. New bonds are formed during compound formation. The bonds may be molecular or ionic.
No new bond formation takes place. Compounds have fixed melting and boiling points. Mixtures do not have fixed melting and boiling points. Example: Salt and water, Sugar and Water, Air, etc. Compounds can be considered as pure substances.
Mixtures are considered impure substances. Sample Questions Question 1: What do you mean by mixture? The type of bonds holding together in a compound can vary i. The elements are present in a fixed ratio whether it is available in any compound. There are some examples of the compound mention below that help to understand you in a good manner. Example 1- Pure water- It is a compound made from two elements i. In which each molecule of water contains 2 hydrogen atom bonded to a single oxygen atom.
In simple words, the ratio of hydrogen to oxygen in water is Example 2- Pure Methane — This compound is also made up of two elements- carbon and hydrogen in the ratio of Example 3- Pure table salt- The two elements present in pure table salt is sodium and chlorine.
However, these two elements share an equal ratio i. Example 4- Pure Glucose — This is the compound that is made from three elements i. Hydrogen share double ratio than carbon and oxygen — What is a Mixture? A mixture is a substance composed of two or more matter that can be separate with the help of physical methods.
There are some examples of the mixtures that are present around you like a solution of water and salt, sugar and water, different gases, air in the atmosphere and many more. Below are some other examples of a mixture. Examples of Common Mixtures are as Follows:. Seawater - It is a mixture of various salts and mixture. Gunpowder — It is a mixture of Potassium Nitrate and carbon. Ink — It is a mixture of different coloured dyes which can be separated by using Chromatography. Crude oil — It is a mixture of organic compounds that includes hydrocarbons.
Dry Air — It is a type of much different type of gases like nitrogen, oxygen, carbon dioxide, argon, neon, and other tiny traces gases. Air generally contains water vapour as a part of mixture. These are some possible heterogeneous and homogeneous mixtures. In the given example of a mixture, the various components do not combine through any kind of chemical changes.
Therefore, the components mix with others does not lose their individual properties. Moreover, mixtures are divided into types based on their composition.
Types of Mixtures. Homogeneous Mixture. Homogeneous Mixtures are those that have composition throughout their body. For instance - a mixture of salt and water, sugar and water, lemonade, soda water etc. The example of salt and water is a classic example because there is no differentiating between the mixture of salt and water.
The light of passed through the mixture of salt and water is not seen. This kind of mixture has a uniform composition that does not separate readily.
