What is the total volume of 70 percent ethanol from 1600ml ethanol?
To find the total volume of 70% ethanol, you need to divide the volume of pure ethanol (1600 ml) by the concentration of ethanol (0.70). This gives you a total volume of approximately 2285.71 ml of 70% ethanol.
Is 70 percent ethanol is an effective disinfectant for prions?
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.
Why is 70 percent ethanol or any diluted alcohol for that matter better at penetrating cell membranes than undiluted alcohols?
Diluted alcohols like 70% ethanol disrupt cell membranes more effectively because the presence of water helps denature proteins and dissolve lipids in the membrane. This allows the alcohol to penetrate the membrane more easily and destroy the cell. Pure alcohol can evaporate too quickly and may not interact with the membrane effectively.
How many percent of ethanol is not so flammable?
Ethanol is totally burned.
How do you make 100 percent of ethanol from 80 percent ethanol?
To increase the concentration of ethanol from 80% to 100%, you can use a process called distillation. By distilling the 80% ethanol solution, you can separate the ethanol from the water and other impurities, resulting in a higher concentration of ethanol.
