To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.
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.
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.
most "absolute" ethanol used in the lab is 95% ethanol by volume,this is due to the fact the ethanol is very miscible with water so its difficult to remove all the water that is present in the atmosphere,it is possible to get 100 alcohol but it is an awkward process and generally 95 does the job just fine
hmm well the label on everclear does say that its 95% volume,so technically i guess it would be a suitable substitute for 95% ethanol if you were stuck,id still recommend buying the ethanol youd use in a lab unless its for a burner
Nitrogen and oxygen make up more than 95 percent of an inhaled breath. Nitrogen accounts for about 78 percent, while oxygen makes up around 21 percent.
1. Extract 959,6 mL from the 99 % solution. 2. Add 40,4 mL water.
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%)
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.

95 ml of ethyl alcohol to 5 ml of water
To prepare 100ml of 70% Ethanol, measure 70ml of 95% ethyl alcohol in a graduated cylinder and add 30ml of distilled water. To prepare 100ml of 70% Ethanol, measure 70ml of 95% ethyl alcohol in a graduated cylinder and add 30ml of distilled water.
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.
according to me, ethane can't be prepared from ethanol. but you can prepare ethene from ethanol by treating ethanol with conc. H2SO4 (95%) In 440 K Temperature with release of water molecule.
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.

No, alcohol cannot be 100 percent pure in practical terms. Ethanol, the type of alcohol commonly used in beverages, can be distilled to a very high concentration, typically around 95% purity, but reaching absolute 100% purity is challenging due to the presence of water and other impurities. Additionally, even in laboratory settings, achieving 100% pure ethanol is difficult because it tends to form an azeotrope with water, which prevents complete separation.
It is an alchoholic compound i.e. 95% ethanol.
