What is the Difference Between Pure Substance and Mixture?
🆚 Go to Comparative Table 🆚The main difference between a pure substance and a mixture lies in their composition and properties. Here are the key differences:
- Pure Substance: A pure substance has a constant and definite composition, meaning that all samples of the substance have the same properties and composition. Pure substances can be further divided into elements and compounds. They have constant physical and chemical properties. Examples of pure substances include gold, copper, oxygen, chlorine, diamond, water, salt, and baking soda.
- Mixture: A mixture is a physical combination of two or more pure substances, in which each substance retains its own chemical identity. Mixtures can be classified as homogeneous (uniform composition) or heterogeneous (non-uniform composition). They have varying physical and chemical properties. Examples of mixtures include nitrogen and oxygen in the atmosphere, water and oil, and oil and water.
In summary:
- Pure substances have a constant and definite composition.
- Mixtures are physical combinations of two or more pure substances, with each substance retaining its own chemical identity.
- Pure substances have constant physical and chemical properties.
- Mixtures have varying physical and chemical properties.
