  • When immiscible components of a mixture settle out, the most dense liquid forms which layer?
    The bottom layer
  • This method of separation is based on what physical property?
    Magnetism
  • In water treatment, what is the purpose of sedimentation?
    To remove solid particles from the water
  • In water treatment, what is the purpose of sedimentation?
    To remove solid particles from the water
  • What method of separation is being used here?
    fractional distillation
  • In paper chromatography, the dye the move furthest up the paper is ( LEAST SOLUBLE / MOST SOLUBLE )
    most soluble
  • A solution can be separated into it's components using the separating funnel. (TRUE or FALSE)
    FALSE
  • Name two methods of separation that depend on the density of components.
    Decantation, sedimentation, centrifugation, and using the separating funnel all depending on the density of the components of the mixture.
  • How would you separate liquids of similar boiling points?
    fractional distillation
  • In water treatment, what is the purpose of sedimentation?
    To remove solid particles from the water
  • Some solid-liquid mixtures are separated by filtration. what other type of mixture can be separated using filtration?
    Gas-gas or solid-gas
  • Some mixtures require more than one method to completely separate all components. (TRUE or FALSE)
    TRUE
  • A bottle containing two different liquids is covered and shaken. The mixture is not homogenous and quickly separates to form two layers. What word can be used to describe the two liquids?
    The two liquids are IMMISCIBLE.
  • In a medical lab, what method is used to separate the components of blood.
    centrifugation
  • what method of separation is being used here?
    centrifugation
  • What is volatility?
    Volatility is how readily a substance evaporates.
  • What method of separation is being used here?
    filtration
  • Name two methods of separation that may depend on particle size.
    Filtration, sieving or hand picking may be used to separate mixtures based on the sizes of component.
  • What is the most appropriate method of separation to be used here?
    hand-picking
  • What three factors determine what method of separation that will work best?
    The type of mixture, the physical properties of components, and quantity to be separated should all be considered.
  • What method of separation is being used here?
    simple distillation
  • Hand- picking can be used to separate mixtures based on the colour of components. (TRUE or FALSE))
    TRUE
  • What method of separation is being used here?
    (paper) chromatography
  • What is centrifugation?
    Centrifugation is a method of separating components of a mixture using high speed rotation
