SEPARATION TECHNIQUES Filtration and Evaporation Distillation Paper Chromatography

Filtration and Evaporation Filtration is a method for the separation of the parts of a heterogeneous mixture. When students mixed two common substances, a heterogeneous mixture was formed. There was a precipitate in a solution.

Filtration and Evaporation In preparation for the filtration, the filter paper must be folded into a cone. The students may be measuring the mass of the filter paper so that they can determine the mass of the precipitate after the experiment.

Filtration and Evaporation The cloudy, heterogeneous mixture is carefully poured into a funnel that has been set up with filter paper. Notice that the filtrate is being collected in a beaker.

Filtration and Evaporation The precipitate in the original filtrate beaker must be washed out using the stirring rod and the wash bottle.

Filtration and Evaporation Evaporation is a method for separating the components of a homogeneous mixture. After filtration, the students evaporated the filtrate solution to separate it from any dissolved solute.

Filtration and Evaporation The liquid (solvent) from the filtrate solution will evaporate leaving behind any dissolved solute.

Filtration and Evaporation Meanwhile, the insoluble solid that was collected on the filter paper was dried in an oven. By taking the mass of the filter paper before the filtration and the mass of the paper and solid after it dries… …the mass of precipitate can be calculated

Distillation Distillation is a method for the separation of the components of a homogeneous mixture. The basis for separation is the different boiling points of the components in the liquid.

Distillation The distillation apparatus will be used to separate some of the components of imitation vanilla.

Distillation The component with the lowest boiling point will boil off first. The vapor is condensed and this distillate is collected in the receiving flask.

Distillation When all of a particular component is gone… …the temperature will rise to the next boiling point and that substance will form the next distillate.

Imitation Vanilla Flavor Ingredient Chemical formula Boiling point (1 atm) Water H20 100C propylene glycol C3H8O2 188C vanillin C8H8O3 285C caramel color mixture of complex sugars N/A 0.1% sodium benzoate NaC6H5CO2 phosphoric acid H3PO4 158C ethyl vanillin C9H10O3

Paper Chromatography Paper chromatography is an easy way to separate the soluble components of a homogeneous mixture We will perform a chromatographic sparations of the pigments in felt pens

Paper Chromatography Specific vocabulary words include: Mobile phase Solvent Stationary phase Paper Separation is based on: Solubility of the sample in the mobile phase Molecule size (and other factors)
