Why only 70 percent alcohol as disinfectant not more or less concentrated?

because the 100% alcohol is inhibited the protein synthesis but can not reach at the nucleic acid and it create an protective layer out side the cell membrane but 70% alcohol is more aqueous than the 100% alcohol and reaches easily in the whole cell and inhibited the protein synthesis the cell may lead to died thats why only 70%alcohol is used as chemical disinfectant....

What is a term used for a less concentrated solution?
A DILUTE solution is the usual terminology for a less concentrated solution.
Where is water moving from in osmosis?
It move from the more concentrated place to the less concentrated place.
What is the difference between concentrated and diluted?
The terms concentrated and diluted refer to the various states of a solution. When it is concentrated, there is more solute or less solvent. In contrast, when it is diluted, there is less solute or more solvent.
Why is acid transported in concentrated form than diluted?
It is less costly to transport acid in concentrated form because it weighs less and takes up less volume than a diluted form.
Why use of alcohol is preferred over mercury in thermometers?
Alcohol is less expensive and the compounds formed from oxides of Mercury are poisonous while alcohol is less problematic.
In medicane is alcohol considered a disinfectant?
Yes, if the alcohol has a high enough alcohol has around a 90% potency (180 proof), some times way less can also do good, like a 50% (100 proof) can be effective to disaffectent a wound.
Why is pure alcohol more dangerous than adulterated alcohol?
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.
Which has more alcohol in it a solution of one percent by volume or one percent by weight?
One percent by weight. Alcohol has a density of less than water, so 1 g of alcohol is more than 1 mL.
What is the percent of alcohol in rock and rye?
Most whiskeys (rye) are 86 proof. Percent is half that so they are 43% alcohol. When mixed with anything in a drink they become diluted -- less alcohol %
Why is alcohol 70 percent?
Isopropyl rubbing alcohol is usually around 70% (by volume) because this is the optimum concentration for its action as a disinfectant. At lower concentrations it is not as effective. However at higher concentrations its effectiveness declines because of the way in which it works. Alcohol kills cells in the target organisms by causing the coagulation of proteins which it contacts. If very strong alcohol is used then it penetrates the cell wall of the organism and coagulates the proteins which are immediately inside the cell wall and this mass of coagulated protein protects the inner parts of the cell from the alcohol. Then, if conditions improve, the cell can recover. Alcohol which is less concentrated works in the same way but because it coagulates the proteins more slowly, more of the alcohol is able to penetrate deeper into the cell and so is more effective in destroying the cell.
Why is 70 percent isopropyl alcohol more expansive than 40 percent isopropyl alcohol?
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.
A semipermeable membrane has an 8 percent salt solution on the left side and a 9 percent on the right side what will most likely occur?
There will be movement of water by osmosis from the less-concentrated solution (left) to the more-concentrated solution (right). Water will tend to flow from a more-dilute state to a less-dilute state.
Does miller 64 have less alchol than other beers?
Yes, it has much less alcohol, only 2.8 percent.
What is a term used for a less concentrated solution?
A DILUTE solution is the usual terminology for a less concentrated solution.
If i add 40 percent alcohol plus 7 percent alcohol is it more alcohol?
More than what The final alcohol content would be somewhere between 40% and 7% alcohol by volume depending on how much of each you have. To answer the question, the resulting solution would be less alcoholic than the 40% and more alcoholic than the 7%.
The net flow of molecules from less concentrated to more concentrated solutions is?
Osmosis
Are the Sun's rays more or less concentrated in December?
less
