Experimental Techniques

Question 1

Fractional distillation

Answer 1

Has the main idea of simple distillation just works with more then 2 substances and is a more complicated process but it separates the mixture depending on the boiling point

Question 2

simple distillation

Answer 2

separates two liquids by heating them up till one of the liquids starts to boil and the gas then goes into a condenser where the cold makes the gas condense and then you have the two sperate liquids

Question 3

Chromatography

Answer 3

molecules in mixture applied onto the surface or into the solid, and fluid stationary phase is separating from each other while moving with the aid of a mobile phase.

Question 4

Crystallisation

Answer 4

if a saturated hot solution is allowed to cool, the solute is no longer soluble in the solvent and forms crystals of pure compound (also works with evaporation)

Question 5

Filtration

Answer 5

The process of separating an insoluble solid from a liquid through a filter paper. The liquid can go through but the solid builds up on the filter paper

Question 6

solvent

Answer 6

the substance in which the solute is dissolved (liquid)

Question 7

solute

Answer 7

the substance that dissolves in a solvent to produce a mixture

Question 8

solution

Answer 8

a mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility

Question 9

substance

Answer 9

a matter which has a specific composition and specific properties

Question 10

mobile phase

Answer 10

Liquids and gases are in the mobile phase because they flow and the phase implies moving

Question 11

stationary phase

Answer 11

Solids are in the stationary phase, it means they don’t move

Question 12

Chromatograms

Answer 12

The product of chromatography

Question 13

solubility

Answer 13

How well something dissolves

Question 14

insoluble

Answer 14

That a substance doesn’t dissolve in a solvent
