Difference between mixture and compound
Mixture | compound |
---|---|
The Constituents of a mixture may be present in any ratio, |
The constituents of a compound are always present in a fixed ratio by mass or weight |
Mixture may be homogeneous or heterogeneous. | Compounds are always homogeneous in nature |
The constituents of a mixture can be easily separated by simple mechanical means | The constituents of a compound cannot be easily separated by simple mechanical means chemical method is Required. |
The properties of a mixture are in between those of its constituents. | The properties of a compound are entirely different from those of its constituents. |
Mixture are formed as a result of physical change | Compounds are formed as a result of a chemical change |
The melting and boiling points of a mixture are usually not sharp. | Chemical Compounds possess sharp melting and boiling points |
When a mixture is formed no heat, light or electrical energy is absorbed or evolved. | Formation of a compound is always accompanied by absorption of heat ,light or electrical energy. |
Difference between homogeneous and heterogeneous mixtue
Homogeneous mixture |
Heterogeneous mixture |
---|---|
A mixture which contains the uniform composition through out the sample is called homogeneous mixture.The components of this mixture cannot be seen with naked eye or even under a powerful microscope. It consists of a single phase i.e Either gaseous, solid or liquid for example, air is a mixture of different gases. whereas petrol, kerosene oil, diesel oil etc. are homogeneous mixture of a number of liquid hydrocarbons. Homogeneous mixtures are also called solutions. | A mixture which does not contain the uniform composition throughout the sample is called the Heterogeneous mixture. The components of this mixture can be seen even with a naked eye. It consists of two or more distinct phases. A mixture of sand and copper sulphate is an example of heterogeneous mixture. Mixture can not be represented by a formula because it is a component of two or more elements or compound mixed in any proportion. |
