Hi

 

I have do to a science project for my school. I choose to use listerene in a boiling point separation experiment. They will let me use all of the classroom equipment, but I have to figure out EVERYTHING else (because our books aren't too specific :confused:). I have to distell 250ml of listerene and separate the alcohol and the water out of it. How do i set up this experiment?

 

Also fyi they said that its fine if i ask for help on science-related forums

 

oops i meant boiling point separation.

Before doing anything at all, first study the following ("Study? I thought I was going into the lab"... yes: study).

 

1. Start with listing all the components in listerene.

2. Find out how much of each component is present in listerene.

3. Find the boiling points of all the components

 

4. Read http://en.wikipedia.org/wiki/Distillation - and make sure you understand it! (It's also for your own safety that you must understand it... distillation is not entirely without dangers! You will be evaporating flammable chemicals at a rate that's high enough to keep a nice fire going!)

 

5. Check which of the components will be the first to boil (lowest boiling point).

6. Check which is second to boil... etc.

7. Check which of the major components (present in large amounts) will be the first to boil.

 

Try to understand what will happen when you will heat the liquid to its boiling point...
