always wondered why it turns white when you add water to it.
Is it some kind of chemical reaction?"
Trying to remember chemistry O level now. Something about the water and the essential oils in ouzo forming a precipitate and that makes it cloudy. Not a chemical reaction, nothing so drastic!
I doubt you study the reaction of 'anithole' in 'o' levels but you are not far off. The aniseed oil is insoluble in water and very soluble in alcohol. So when the water is added the ''anise' will come out of solution as you guessed.
At last you are talking sense . . . your specialty Sir?
I did make ouzo/raki in the lab and performed experiments with the produce. My students thought I should go in to business
That's illegal
Although I must say we had a Ph.D. student who used the lab quick-fit distillation equipment to make sloe-gin
Distilling to produce the alcohol would be illegal.
I extracted the anise using the Soxhlet extractor. The ethanol readily available. No illegalities from me. But still would have been able to distil ethanol in small quantities without breaking the law.
Lab ethanol has benzene added to stop people using it in this way and then selling it. You would have had to re-distill the ethanol . . . unless you bought Molecular Biology grade EtOH. Actually GC-Mass Spec EtOH should be the same.
Are we on the same wavelength . . . .
You dont think I drink the stuff do you. Perier water had more Benzene in it that the EtOH I used.
. . . another fine reason for people to stop buying environmentally unfriendly bottled water.
You are of the generation that used to mouth pipette benzene and toluene, etc with total disregard . . . do you remember?
Thanks for the reminder of my age.
The worst we did was smoking the Kymograph drums using a Benzene burner in a confined space.
I loved that smell. I am still alive too. Lucky me.
