simple distillation

Question 1

what can distillation be used for?

Answer 1

to separate a liquid from a solid if we want to KEEP the liquid

Question 2

name everything needed to carry out a simple distillation experiment.

Answer 2

thermometer
mixture in a flask
liquid + dissolved solid
condenser 
glass tube

Question 3

what is the glass tube surrounded by?

why?

Answer 3

the condenser with 2 holes for cooling water to go in and out continuously to cool down the liquid

Question 4

describe fully how to separate a liquid from a solid using simple distillation

Answer 4

1. the solution is heated (by a bunsen burner e.g)
2. when the liquid is heated, it starts to evaporate, turning into a vapour
3. this vapour rises up the glass tube
4. the thermometer shows us that the temperature is rising(but we usually just boil the liquid in simple distillation)
5. the vapour now passes into the condenser
6. the condenser is kept cold with continuous running water
7. this turns the vapour into liquid that passes into the beaker
8. we are left with crystals of our solid in the flask
9. and our liquid in the beaker

Question 5

simple distillation can be used to produce for drinking water from sea water, but we choose not to. why?

Answer 5

a great deal of energy is required to produce drinking water from sea water through simple distillation
