Coffee... the solution to all of life's problems :thumbsup: (Or just caffeine in general)

Alcohol. The cause of... and solution to... all of life's problems
Despite what many will tell you: chemically, alcohol is a solution.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

That would be (more specifically) a tincture,* but alcohol makes them and isn't one, itself. But, it is true that 1 - you can find solutions with alcohol 2 - it is a way to bring about solutions (Vodka: tincture of water. I'm not sure if there's such a thing as tincture of alcohol) * Amalgam of understanding: A tincture is a solution, although a solution isn't always a tincture, so I'm just getting you warmed up for ToD.

Well...yes and no... A solution is defined as:
Quote:
"a homogeneous mixture composed of two or more substances"
Pure alcohol alone would not constitute a mixture of multiple substances and would therefore not be a solution. But in English the word "alcohol" is also commonly used to refer to many recreational drinks containing ethanol in addition to other types of molecules. Plus, there are two other problems: 1) Pure ethanol can't be created via distillation as the water-ethanol mixture is azeotropic. 2) Pure ethanol can't be consumed: even "lab grade" ethanol isn't "pure" and you really don't want to drink that, it's got far too much methanol in it (the ethanol / methanol mix is also azeotropic) and that does really nasty things to you very quickly. If you did get hold of 100% ethanol, it would poison you in a pretty small dosage, as well as probably evaporating extremely quickly if you tried to sip it!

Recall that in real life I was a real chemist. The 'a homogeneous mixture' quote isn't quite sufficient: it must be homogeneous on a molecular level (ionic is OK) - and a characteristic is that it is transparent* (homogenized milk is not a solution) - it is a colloid. Colloids are homogeneous. So homogeneity is necessary, but not sufficient. If you've ever had a "Bob Marley" on vacation, it might not even be necessary to be homogeneous - as you've several distinct solutions in a single container. Pure ethanol is obtained by adding a bit of benzene (C6H6) to the alcohol/water mixture. An even lower boiling azeotrope exists consisting of benzene/water/ethanol. I used to remove traces of water by boiling the ethanol with magnesium turnings (for a while) and then collecting the distal late (see: reflux condenser). Lab grade alcohol DOES NOT contain methanol. Denatured alcohol does. Lab grade alcohol, as you call it, is the (multiply distilled) azeotrope (ca. 190 proof). Other than the expected water component it would contain nothing else (and wasn't taxed!). We used some 200proof (i.e., pure alcohol) available in pint bottles (w/a no-tax tax stamp) for the solvent in a flashlamp pumped dye laser. To recycle the stuff (for reuse or eventually pouring into my car's gas tank) I used the above mentioned magnesium methodology. Using methanol instead of benzene (for dehydration) has been found unsuitable (a good thing, too: methanol is scary stuff). The main problem (as a consumer) with the pure (200 proof) ethanol is that it can cause tissue damage as it somewhat aggressively sucks water out of your cells to dilute itself. Alcoholic beverages always do this to a small extent, but it gets more powerful with the difference in alcohol/water content between your cells and what you're drinking. (In the cases of some people, this osmosis may be reversed after they drink enough, such as Nagy) Next lesson: vesicles and pellicles

:thumbsup: I bow to your vastly superior knowledge! (I thought I was doing pretty well to remember the word "azeotropic" and the meaning was a bonus - though I had to google how to spell it - it's been 35 years since my last chemistry lessons!)
