A) They are [CH3-CHOH] identical; and B) the distillation process is what transforms ethanol into eventually a pure form.
Ethanol is a pure substance, but it is rare to encounter it pure. Laboratory alcohol usually contains small amounts of water and methanol. Alcoholic drinks contain large quantities of water, as well as flavourings.
Corn is first ground into a fine powder, which is then mixed with water and enzymes to break down the starch into smaller molecules. Yeast is then added to ferment the sugar into ethanol, carbon dioxide, and heat. The mixture is distilled to separate the ethanol from the other components, resulting in pure ethanol.
No, since the ethanol is pure it is a base and will make the alluminium turn all black and rusty. Hope this helped :-)
Well, darling, you can't make 90% ethanol from 100% ethanol because, sweetie, 100% means it's already pure ethanol. You can dilute it with a calculated amount of water to get to 90%, but you ain't changing that 100% ethanol into something else. So, mix it up with water like a fancy cocktail and voilà, you've got yourself some 90% ethanol.
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.
Industrial distilled ethanol (not from fermentation) can be obtained at 99,999 %.Ethanol from fermentation has a concentration of max. 96 %.
Ethanol..
Ethanol.
Pure ethanol, CH3CH2OH, is an pure organic compound and not a mixture

150 ml ethanol to 350 ml distilled water
Distilled water is pure.
Distilled water is a pure substance. H2O, nothing more.
