Why 70 percent ethyl alcohol is used rather than 90 percent or 95 percent?
Deepak4upilibhit
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.

Does water and ethyl alcohol mix together or create and interface?
Water and ethyl alcohol are both polar solvents, meaning they have similar intermolecular forces and are able to mix together. When they are mixed, they form a homogeneous solution rather than creating an interface between the two liquids. This is because the polar nature of water and ethyl alcohol allows them to interact and dissolve into each other.

Why glycerol is more viscous then ethyl alcohol?
Glycerol (Glycerin) contains three 'OH' groups at adjacent carbon atoms so the chances of ' hydrogen bonding' are higher than normal alcohols and such a liquid is denser than ethyl alcohol so it is more viscous.
What is the difference between ethyl and methyl alcohol?
Methanol, also known as methyl alcohol, is madeof molecules containing one methyl group, with a chemical structure of CH3-OH. Methanol is highly toxic if inhaled, drunk, or absorbed through the skin and can cause blindness. Ethyl alcohol is the same as ethanol or grain alcohol. I has two methyl groups and looks like CH3-CH3-OH. This is the type of alcohol found in the alcoholic beverages people consume. Both compounds are organic and are good solvents and fixatives.
Why 40 percent alcohol cheaper than 70 percent alcohol?

Is grain alcohol more sanitary than rubbing alcohol. I have been using grain alcohol for antibacterial usage rather than using the gel antibacterial lotions. But grain alcohol costs 15 per liter.?
"Grain alcohol" is ethyl alcohol (ethanol). Gel antibacterial lotions are typically somewhere around 70% ethyl alcohol. Ethyl alcohol is most potent as an antiseptic when diluted slightly with water to somewhere around that 70% ethyl alcohol range. If you're buying "grain alcohol" that is 190 proof (95%) or greater, and using it straight as an antiseptic, then you're not getting the best value for your money.Rubbing alcohol is typically 70% isopropyl alcohol. It too is a good antiseptic.The gel antibacterial lotions are easier to apply, less messy, and they contain emollients that prevent the skin from being dried out by the alcohol. Generally speaking they are the best solution to the problem, combine with thorough washing several times a day.As for which is better, I suppose it all comes down to concentration and application, but all should work just fine.
Why is pure alcohol more dangerous than adulterated alcohol?
