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.
1) take 10gm of gentian violet. then add to them: 2) Alcohol 70% ( H2O).... to 1000 ml
prepare it
90% of 90 = 90*90/100 = 81
90 - 90 = 0
Your question is incoherent. Please rephrase.
Yeast creates alcohol from sugar.
To prepare 1000 ml of 70% alcohol solution, you would need to mix 700 ml of 95% alcohol with 300 ml of water. Starting with a base of 95% alcohol ensures that the final solution will be at least 70% alcohol.
To prepare 1 liter of a 5% alcohol-water solution, you would mix 50 mL of alcohol with 950 mL of water. This ratio would give you a total volume of 1 liter with 5% of it being alcohol.
No, 90% isopropyl alcohol and grain alcohol are not the same. Isopropyl alcohol is a type of alcohol used for cleaning and disinfecting, while grain alcohol is a type of alcohol often used for consumption purposes in beverages. They have different uses and properties.
Add 5% water
Virtually all alcohol is metabolized by the liver. However, a very small percentage of alcohol is lost through respiration and perspiration.
Pure alcohol is required to prepare homeopathic medicines . it may be used as absolute alcohol or Rectified alcohol . it must not be methylated .
The liver is the primary organ responsible for oxidizing 90 percent of the alcohol consumed. It converts alcohol into acetaldehyde and then into acetate through a process involving enzymes like alcohol dehydrogenase and aldehyde dehydrogenase.
The liver is the organ that oxidizes 90 percent of alcohol. This organ is responsible for processing all toxins in the body. Excessive intake of alcohol can cause permanent damage to the liver.
It doesn't.
90 proof means the alcohol content is 45%, by volume.200 proof = 100%180 proof = 90%and so on.
