Pure Substance vs Mixture — Comparison Table
| Basis | Pure Substance | Mixture |
|---|---|---|
| Composition | Fixed, definite composition | Variable composition possible |
| Number of Components | Single type of particle or element/compound | Two or more substances combined |
| Properties | Fixed, definite properties | Properties vary based on composition ratio |
| Melting Point | Sharp, definite melting point | Range of melting points |
| Separation | Cannot be separated by physical methods | Can be separated by physical methods |
| Example | Pure water, pure gold, oxygen gas, salt | Salt water, sand and gravel, air, brass |
Key Points
- Pure substances can be elements or compounds
- Mixtures retain individual properties of their components
- Pure substances have constant physical and chemical properties
- Chemical analysis is needed to identify pure substance components
