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....

Why 70 percent alcohol is used as disinfectant?
A 70% alcohol solution is effective as a disinfectant because it has the optimal concentration to penetrate bacterial cells and denature proteins, effectively killing them. Higher concentrations of alcohol can evaporate too quickly and be less effective at killing bacteria, while lower concentrations may not be as potent.
What are the differences between isopropyl and acetone, and how do they compare in terms of their uses and properties?
Isopropyl and acetone are both solvents, but they have different chemical structures. Isopropyl alcohol is a type of alcohol, while acetone is a type of ketone. Isopropyl alcohol is commonly used as a disinfectant and cleaning agent, while acetone is often used as a solvent for paints and nail polish. Isopropyl alcohol is less volatile and less flammable compared to acetone.
What is the difference between acetone and rubbing alcohol?
Acetone and rubbing alcohol are both solvents, but they have different chemical compositions and properties. Acetone is a type of ketone, while rubbing alcohol is a type of alcohol. Acetone is more volatile and flammable, while rubbing alcohol is less volatile and flammable. Additionally, acetone is commonly used as a nail polish remover, while rubbing alcohol is often used as a disinfectant.
What are the differences between isopropyl alcohol and acetone in terms of their chemical properties and uses?
Isopropyl alcohol and acetone are both solvents, but they have different chemical structures and properties. Isopropyl alcohol is a type of alcohol with the chemical formula C3H8O, while acetone has the formula C3H6O. Isopropyl alcohol is less volatile and less flammable than acetone. Isopropyl alcohol is commonly used as a disinfectant and cleaning agent, while acetone is often used as a solvent in nail polish remover and paint thinner.
Why 70 percent alcohol used in laboratory?
70 percent alcohol is used in laboratories because it has a higher penetrative power than higher concentrations, allowing it to effectively disrupt the cell walls of microorganisms. It also evaporates more slowly than higher concentrations, providing more contact time for disinfection. Additionally, 70 percent alcohol is less flammable and less likely to damage surfaces compared to higher concentrations.
Why 70 percent alcohol is used as disinfectant?
A 70% alcohol solution is effective as a disinfectant because it has the optimal concentration to penetrate bacterial cells and denature proteins, effectively killing them. Higher concentrations of alcohol can evaporate too quickly and be less effective at killing bacteria, while lower concentrations may not be as potent.
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 %
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 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.
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.
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 are the differences between isopropyl and acetone, and how do they compare in terms of their uses and properties?
Isopropyl and acetone are both solvents, but they have different chemical structures. Isopropyl alcohol is a type of alcohol, while acetone is a type of ketone. Isopropyl alcohol is commonly used as a disinfectant and cleaning agent, while acetone is often used as a solvent for paints and nail polish. Isopropyl alcohol is less volatile and less flammable compared to acetone.
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%.
What is the difference between acetone and rubbing alcohol?
