What is the Difference Between Pure Substance and Homogeneous Mixture?
🆚 Go to Comparative Table 🆚The main difference between a pure substance and a homogeneous mixture lies in their composition and properties. Here are the key differences:
- Composition: A pure substance is composed of a single element or compound, while a homogeneous mixture is composed of multiple different elements or compounds that are uniformly distributed throughout the mixture.
- Uniformity: A pure substance has a constant composition and properties that are uniform across the sample, while a homogeneous mixture has a variable composition.
- Separability: Pure substances cannot be broken down or separated into new products, while homogeneous mixtures can be separated using different separation methods.
- Physical and Chemical Properties: Pure substances have constant physical and chemical properties, while mixtures have varying physical and chemical properties.
In summary, a pure substance is a form of matter with a constant composition and uniform properties, while a homogeneous mixture is a combination of multiple elements or compounds with varying properties.
Comparative Table: Pure Substance vs Homogeneous Mixture
Here is a table comparing the differences between pure substances and homogeneous mixtures:
Feature | Pure Substance | Homogeneous Mixture |
---|---|---|
Composition | Single element or compound | Two or more compounds (or elements) mixed uniformly |
Separability | Cannot be broken down into simpler substances | Can be separated into its components using various methods |
Physical and Chemical Properties | Has constant physical and chemical properties | Has varying physical and chemical properties |
Examples | Iron, water, salt | Salt dissolved in water (solution) |
A pure substance is composed of a single element or compound and cannot be broken down into simpler substances. On the other hand, a homogeneous mixture is a combination of two or more compounds (or elements) that are mixed uniformly, and its components can be separated using various methods. The physical and chemical properties of pure substances are constant, while those of homogeneous mixtures vary.
