Distillation

Distillation is a technique to separate different liquids from each other, this technique is based in the fact that different liquids have different boiling points. If we can heat the mixture and maintain the temperature at one of the liquids boiling point turn this liquid into a gas, trap and condense this gas, we will have removed one of the liquids from the other.

OC2 separate mixtures using distillation

Apparatus

Boiling flask, liebig condenser, beaker, bunsen burner, retort stands

Method

  1. Gather the equipment needed
  2. Fill the boiling flask with the liquid to be distilled
  3. Set up the apparatus so the gases from the boiling flask pass through the condenser.
  4. Connect a tube to the cold water tap and attach it to the liebig condenser
  5. Light a bunsen burner and heat the liquid until it boils
  6. Collect the distillate in a flask.

Results

We Distilled ___________ and got ______________

Conclusion

We can separate 2 liquids from each other by distillation

Distillation is the recondensing of evapourated water, to purify it

Might try to simple distill tea?

All alcohol spirits are distilled, this means that the alcohol is purified from where it was fermented. While the alcohol evaporates at 79oC, the still is maintained at this temperature. However while water boils at 100oC, we know it evaporates at temperatures below 100oC, (otherwise how would puddles disappear?) so we find that it is very hard to get pure alcohol by distillation, which is probably quite a good thing in reality!

SeaWater Recipe

the salt of the oceans comes from the dissolution of rocks, both underwater and on the surface.

Probably the planet's water,in very remote times, from comets. The seas grew as the earth cooled, dissolving in the process numerous salts present in the rocks. Rain contributed to the process by dissolving the surface salts. Today althought the Salinity of different seas is quite varied, it is estimated that there are 36 grams of Salt in every litre of seawater.

Warmer seas are saltier than colder seas.
