Question
Distinguish between compounds and mixtures.
| S.No. | Compounds | S.No. | Mixtures |
| 1. | Compounds are formed as a result of chemical reactions between two or more elements or compounds. | 1. | Mixture is formed by simply mixing two or more constituents. There are no chemical reactions between the constituents. |
| 2. | The components of a compound are always present in a definite ratio by mass. | 2. | The components of a mixture may be present in any ratio. |
| 3. | The properties of a compound are entirely different from its constituents. | 3. | The properties of a mixture are the same as those of its constituents. |
| 4. | Compounds are always homogeneous in nature. | 4. | Mixtures are usually heterogeneous (except in solutions). |
| 5. | Compound formation is accompanied by absorption or evolution of light, heat or electrical energy. | 5. | Heat, light or electrical energy may not be evolved or absorbed during the formation of a mixture. |
| 6. | Melting and boiling points of a compound are usually sharp and fixed. | 6. | Melting and boiling points of a mixture are usually not sharp and fixed. |
| 7. | The constituent elements of a compound can not be separated by any physical method. Special chemical methods or electrochemical methods are employed to separate them. | 7. | The constituent elements of the mixture can be easily separated by physical means. |
| 8. | For example, Water, Carbon dioxide. | 8. | For example, A mixture of iron filings and sulphur. |
