Seperation techniques Flashcards
What are mixtures?
Mixtures are different substances found together, but not chemically bonded. This means they can be separated from each other.
What is a compound?
In a compound different substances are chemically bonded together.
What are solutions?
Solution is a type of mixture made of two parts, the solvent a liquid that makes up most of the solution and solid substance that is added to the solvent in dissolves into it.
What is solubility?
The solubility of a solute means how much solute can dissolve in a certain volume of solvent.
What three things can alter the solubility of a solute?
Different songs have different solubility in different solvents increasing the temperature of the increase is the solubility and soluble substances can dissolve insoluble substances cannot.
What does it mean when you say something is saturated?
Saturated is one so much so You has been added to the solvent that no more dissolve, so we say the mixture is saturated.
What are the four different types of filtration techniques?
Filtration, chromatography, distillation, and evaporation
Explain the stages of filtration.
Filterpaper has extremely small holes in it so the particles in a liquid or solution is so tiny that they can fit through the holes, large particles of a solid, too big to fit through the holes and help back by the paper. This leaves residue and the filtrate, which will be the liquid that passes through the paper, and the residue will be the solids left behind in the filter paper.
Explain chromatography.
A mixture like ink is placed on a piece of paper which is placed in a solvent. As a solvent moves up the paper at separate all the different parts of the ink producing a chromatogram.
Explain distillation.
A method that separate, a soluble in a solvent while keeping the solvent, the solution is boiled to the solvent turns into a gas. The gas has been cool down in the condenser where it turns back into a liquid and can be collected.
Explain evaporation.
A method to separate a soluble in a solvent keeping the solute, the solution is heated then left in an evaporating basin until all the solvent evaporates. The Solute is left behind as a solid.
