A coffee filter is used to separate coffee liquid from ground, this is a suitable example of _____________.
decantation
distillation
filtration
crystallisation
It is a method used to separate liquid and a heavy insoluble solid like soil by allowing the solid to settle at the bottom of the container then the liquid above the solid is poured off carefully into another container.
(a)
Which of the following does not exist as an analytical method?
solid-solid chromatography
solid-liquid chromatography
liquid-liquid chromatography
gas-liquid chromatography
What analytical technique is shown in the image?
(a)
What method of separating components of a mixture is shown in the image above?
(a)
Panning is a method used to separate particles with higher specific gravity (like gold) from the soil/gravel mixed with it. By slowly swirling the water in the pan, the soil is suspended and is poured off slowly. This is an example of:
Filtration
Decantation
Magnetic separation
Evaporation

To remove unwanted materials
To obtain important substances
To obtain pure substances
To obtain impurities
Which of the following shows separation method for evaporation?
What properties does paper chromatography make use of to separate its components?
adsorption and solubility
vapor pressure and boiling point
viscosity and concentration
specific gravity and density
What is the correct technique for removing a precipitate from a solution?
Distillation
Filtration
Crystallisation
Centifugation
