Pure Substances
- A pure substance has a uniform composition and fixed properties, and it can be either an element or a compound.
Physical Properties of Mixtures
- The physical properties of a mixture, such as color, odor, or melting point, are a combination of the properties of its components.
Pure Substance Examples
- Examples of pure substances include water (H2O), salt (NaCl), and sugar (C6H12O6), which have fixed compositions and properties.
Components and Substances
- The components of a mixture can be separated by physical means, such as filtration or sedimentation, whereas the components of a pure substance cannot be separated by physical means.
