70% has more water, thus more readily absorbed by cells. tricks the cells into admitting it
a) 70% ethanol has been found to b most effective in killing microbes.Higher or lower concentrations may not b as effective. b) if u use 90% or absolute ethanol, it will evaporate fast and may not be much effective. c) using higher concentrations will leave its traces on the applied surfaces d) higher concentrations of ethanol are harmful to skin and makes it dry pretty a) 70% ethanol is most effective.higher or lower ones r not as effective b) it evaporates at a slow rate than 90% or absolute ethanol. therefore it is more effective and saves ur ethanol too.. c) higher concentrations alwez leave traces applied surfaces thus addind an unwanted reagent d) 70% ethanol is comparatively less harmful to ur hands.. higher concentrations makes ur skin dry..
70 percent ethanol is more effective at killing microbes than 100 percent ethanol. This is because the addition of water helps to denature proteins and disrupt cell membranes in the microbes, leading to better penetration and more efficient sterilization. Additionally, 70 percent ethanol is less volatile and evaporates more slowly, allowing for longer contact time with the microbes.
70% is the most effective concentration to denature poteins so killing bacteria. At 95% the ethanol just evaporates and leaves the protein untouched. Below 70% does not denature proteins. It also makes the ethanol less flammable.
Absolutely, recent painstaking scientific research has showed that 70% ethanol is the same as 70% ethanol.
70% ethanol is commonly used in laminar air flow chambers because it effectively disinfects surfaces by killing a broad spectrum of pathogens, including bacteria and viruses. The 70% concentration is more effective at penetrating the cell wall of microorganisms compared to higher concentrations of ethanol. Additionally, the lower ethanol concentration helps reduce evaporation, ensuring longer contact time with the surfaces being disinfected.
The question cannot be answered because it does not specify:more effective than what, andmore effective at doing what.
100% alcohol is more effective because of the more alcohol concentration in the drink.
No, 70 percent ethanol is not effective in disinfecting prions. Prions are highly resistant to common disinfection methods, including alcohol-based solutions. Specialized procedures involving harsh chemicals or autoclaving at high temperatures are required to effectively deactivate prions.
to save the ethanol
If I understand you correctly, we are trying to find the volume of 70% of 1600 ml of ethanol. That said: here is how you do it:1. Change 70% into a decimal. You do this by moving the decimal point two places to the right. This would turn 70 into .702. Multiply .70 x 1600.3. The answer is: 1120mL.
To make 70% ethanol from 190 proof ethanol, you can mix 3 parts of the 190 proof ethanol with 7 parts of water. Measure the appropriate volumes of each and combine them in a container, then mix thoroughly to achieve a final concentration of 70% ethanol.
70 percent ethanol means it has 30 percent of water.so due to natural osmosis water can enter thr cell membrane.the ethanol thus moves inside along with water and hence has a beter penetrating power than undiluted ethanol.
