Study Notes
Elements, Compounds, and Mixtures
- Elements, compounds, and mixtures are ways matter can exist.
- Matter occupies space and has mass.
- Pure substances are either elements or compounds.
- Mixtures are combinations of two or more pure substances.
Pure Substances
- Pure substances have a definite composition.
- Elements have a fixed number of atoms of a specific type.
- Compounds have fixed proportions of elements.
- Pure substances have specific melting and boiling points, density, color, odor, and taste.
Mixtures
- Mixtures are made of two or more pure substances.
- Components in a mixture retain individual properties.
- Mixtures do not have a fixed composition.
- Mixtures don't have a specific melting or boiling point.
- Mixtures can be separated by physical means.
Types of Mixtures
- Homogeneous Mixture: Components are evenly distributed and cannot be visually distinguished (e.g., salt solution).
- Heterogeneous Mixture: Components are not evenly distributed and can be visually distinguished (e.g., sand and water).
Separation Techniques
- Various techniques are used to separate components of mixtures based on properties like size, shape, density, boiling point, and magnetic properties.
- Sieving: Separates materials based on size differences.
- Handpicking: Separates materials based on visual differences.
- Sedimentation and Decantation: Separates mixtures based on the settling rate of components.
- Filtration: Separates solid from liquids using a filter.
- Evaporation: Separates a solid from a liquid by vaporizing the liquid.
- Magnetic Separation: Separates magnetic materials from non-magnetic materials.
- Winnowing: Separates lighter materials from heavier materials using wind.
- Froth Floatation: Separates minerals from gangue using air bubbles and chemicals.
- Centrifugation: Separates mixtures based on density differences by spinning.
- Distillation: Separates liquids based on boiling point differences.
- Fractional Distillation: Separates liquids with closely spaced boiling points.
- Sublimation: Separates substances that convert directly from solid to gas and vice versa.
- Separating Funnels: Separates immiscible liquids based on density.
