Topics in Pure Substances & Mixtures: Separation of Mixtures

1

Pure Substances and Mixtures

  • Pure substances are made of only one kind of particle — either atoms or molecules.
  • Elements (like gold) and compounds (like sugar) are pure substances.
  • Mixtures are impure substances formed by mixing two or more substances physically, without any chemical change.
2

Differences Between Compounds and Mixtures

  • Compounds are pure substances formed by chemical combination in fixed ratios.
  • Mixtures are impure substances formed by physical mixing in any ratio.
  • Compounds have new properties; mixtures retain individual properties.
3

Separation Techniques

  • Different methods are used to separate mixtures based on physical properties like size, density, solubility, and magnetic nature.
  • Hand-picking: Removes large impurities by hand (e.g., stones from rice).
  • Winnowing: Uses wind to separate lighter husk from heavier grains.
