Science Purification Test Flashcards
(25 cards)
solute
a minor component in a solution - dissolves in the solvent
solvent
the liquid which the solute dissolves in
soluble
a substance is capable of dissolving
insoluble
a substance is not capable of dissolving
residue
what remains after something has been taken
filtrate
the liquid that has passed through a filter
solution
a liquid mixture in which a solute has dissolved in the solvent
saturated solution
the point at which no more solute can dissolve
dissolve
solid is mixed into a liquid to become a solution
evaporate
particles go from a liquid to gas
boiling
where a liquid bubbles and turns to vapour
condensing
a gas or vapour turns to liquid
filter
to remove solid particles from liquid particles
distillation
purifying a liquid by heating or cooling
chromatography
the separation of a mixture by passing it in a solution or suspension
suspension
where solid particles are mixed in a liquid without dissolving
pure
only one type of particle
particle
a small piece of matter - everything is made up of these
seperate
to remove one type of particle from another
mixture
more than one type of particle
solubility
how much of a substance will dissolve in a solution
what is the independent variable?
what you deliberately change in an experiment
what is the dependent variable?
what you are measuring in an experiment
what are control variables?
variables which you keep the same to ensure that it is a fair test
