The liver is the organ that oxidizes 90 percent of alcohol. This organ is responsible for processing all toxins in the body. Excessive intake of alcohol can cause permanent damage to the liver.
The liver
Add 5% water
No. Grain alcohol is ethyl alcohol. Isopropyl alcohol is a different compound and is not safe to drink.
The highest proof alcohol is about 180 proof or 90% alcohol.
It is true that approximately 90 percent of all alcohol consumed is metabolized by the liver.
If WE Use 90% alcohol it will get evaporated, for 30% alcohol no reaction occurs as water content will be high . so, 70% is used
70% alcohol has been found to be more effective in killing microbes.Higher and lower concentration may not be as effective.90% alcohol coagulate proteins in contact.suppose 90% alcohol is poured over one celled organism,the alcohol penetrate the cellwall of the organism.the coagulated protein would then prevent the alcohol further from the cell and no more coagulation then take place.now,if 70% alcohol is added into one celled organism.The diluted alcohol also coagulates the protein, but at a slower rate,so that it penetrates all the cell before coagulation.Then all the cell coagulated and the organism died.
The answer varies in each different liquor, and should be listed on the bottle as "proof". The "Proof" is twice the alcohol percentage, so 40 proof is 20% alcohol, 180 proof is 90% alcohol.
Alcohol was the thing 90% of the deaths in fraternities had in common according to a 1998 study.
First of all, because technological limits mean that we can only get alcohol at a purity of about 90%. 90% alcohol is also far more expensive than 70%, so it is more cost effective to use 70%. Ignoring all of that, the main reason is that 70% alcohol works just fine and sterilizes object very well.70%alcohol is the efficient concentration to denature the protein.
90 percent of what?
"90 percent" means 0.9, and "of" in arithmetic usually means "times". 0.9 x 90 = 81. 90 percent of 90 is 81.
