∙ 12y agoTo prepare 95% ethanol from absolute ethanol, you can mix 95 mL of absolute ethanol with 5 mL of distilled water. This will dilute the absolute ethanol to the desired concentration. Make sure to mix the solution thoroughly to ensure uniform concentration.
To prepare 1000 ml of 95% ethanol from 1000 ml of 99% ethanol, you will need to add 25 ml of distilled water to the 99% ethanol. This will bring the final ethanol concentration to 95%.
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)
95% ethanol is commonly used in laboratories because it is an effective solvent for a wide range of chemicals and biological substances. It also has antimicrobial properties, making it useful for disinfecting surfaces and equipment. Additionally, 95% ethanol is less prone to evaporation compared to absolute ethanol, providing a more stable solution for various applications.
One has 4.5 percent more alcohol which is important because you can get to a max of 95 percent using fractional distillation. To get the 99.9 percent or absolute alcohol, you need to use other more advanced methods. Some of these include include desiccation using adsorbents.
It is an alchoholic compound i.e. 95% ethanol.
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.
To make a 90% ethanol solution using 100% ethanol, you can simply dilute the 100% ethanol with a calculated amount of distilled water. For example, to make 1 liter of 90% ethanol solution, mix 900 mL of 100% ethanol with 100 mL of distilled water. Be sure to measure accurately to achieve the desired concentration.
Absolutely, recent painstaking scientific research has showed that 70% ethanol is the same as 70% ethanol.
to save the ethanol
According to the CRC Handbook, 70th edition, the density of 94% ethanol is 0.8070 g/ml and the density of 96% ethanol is 0.8013 g/ml. We can interpolate to find that the 95% ethanol should be 0.8042 g/ml.
Silicates make up close to 95 percent of the rocks in the Earth's crust
