Yes, you can get alcohol poisoning from any percentage of alcohol. The high concentration makes it easier to get poisoned with little time for you body to react to the danger.
It also depends on what KIND of alcohol it is. Isopropyl alcohol or any other kind of medical/industrial type (which you CAN actually get in 100%) is dangerous in any concentration. Even drinking a small amount like a small sized bottle can harm or kill you. Now if you are talking about drinkable alcohols (such as grain or anything like that) then yes it can also kill you, but no more than any other alcoholic drink. With these kinds of alcohols it simply becomes what AMOUNT you drink. Hell beer can kill you, but its generally too difficult to physically drink enough to have severe effects because they only have something like 5-10% alcohol content. But there are PLENTY of 150+ proof (which would be 75% and up, proof is simply double the percentage) alcohols like Bacardi 151. Some forms of Absinthe have also been known to be upwards of 90% alcohol content (the hallucinogenic effect is NOT however from the alcohol its from the Wormwood). So theoretically (if a 100% alcohol safe for consumption were available) it wouldnt kill you unless you drank enough to make your blood toxic, it would however be much easier to drink too much and kill yourself with that high of alcohol content.
Fermentation, followed by distillation.

Depends if its a primary, secondary or tertiary alcohol.
Perhaps 100 or 94 proof ( = 50 or 47 percent alcohol) would work better than 80 proof (40 percent alcohol).
That all depends on what you want the final concentration of alcohol to be.
It is difficult and expensive to refine anything to 100% purity. Best to use 70% as it is just as effective and cost a whole lot less.
To make 15% alcohol from 40% alcohol you simply take 15cc of your 40% alcohol and put it into a graduated cylinder and fill the cylinder up the rest of the way with deionised water or distilled water to the 40cc mark on the graduated cylinder. you will then have 15% alcohol from 40%
This is a solution containg 60 percent isopropyl alcohol; can be used as rubbing alcohol.
Perhaps 100 or 94 proof ( = 50 or 47 percent alcohol) would work better than 80 proof (40 percent alcohol).
50% alcohol Proof ÷ 2 = % alcohol
100% alcohol is more effective because of the more alcohol concentration in the drink.
You mix the pure alcohol with something else, for example, water.
Yes
That all depends on what you want the final concentration of alcohol to be.
They sell an 80 proof(40% alcohol) and a 100 proof(50% alcohol).
it means that for every 100 ml of the drink in question 18 ml of that 100 ml will be alcohol
50% alcohol Proof ÷ 2 = % alcohol
If you drink too much of it, yes. You can get alcohol poisoning from any percentage alcohol if you drink too much of it.
100% of the 10%
Pure alcohol is far more dangerous than adulterated alcohol because pure alcohol has one hundred percent alcohol in comparison to aldulterated alcohol which is less than 100 percent.
