Filtration and Crystallysation and water purity

Question 1

What are filters used for?

Answer 1

To seperate some mixtures. They let smaller materials through but not insoluble substances.

Question 2

What is crystallysation?

Answer 2

solutes are seperated from solvents leaving solutes behind

Question 3

what is a solvent?

Answer 3

The thing a solute is dissolve in

Question 4

what is a solute?

Question 6

What is distillation used for?

Answer 6

to seperate liquids in solutions

Question 7

what are anti-bumping granules?

Answer 7

to make the liquid boil more smoothly

Question 8

What can fractional distillation be used for?

Answer 8

seperating different products in crude oil, seperate out gases in the air after it has been cooled and turned into a liquid at -200 degrees. mak alcoholic drinks such as whiskey and vodka

Question 9

how do anti-bumping granules work?

Answer 9

small bubbles or vapour form on them and reduce risk of liquid boiling over

Question 10

Give examples of different ways to purify water?

Answer 10

distillation, sedimentation, chlorination, filtration,

Question 11

Why should water not contain dissolved salts when using it for an experiment?

Answer 11

The results will be inaccurate because you don’t know whether the results are coming from the salts or the water itself.
