I think you can take advantage of the boiling points of the solution and that of the ethanol.ethanol has a boiling point of 78 degree celsius
By fractional distillation. Heat the mixture gently. As the temperature rises both liquids will evaporate and should be cooled and the condensate collected. The temperature will stabilise at around 78 deg C when all the remaining ethanol will evaporate.What you are left with is pure water. The condensate is mainly ethanol with a small quantity of water. It can be distilled again to increase its purity.
Do you have an solution, because N03 Ca is freely soluble. tiãoadd. unimportant fact. Essentially ALL the nitrates are soluble, even Mercurous nitrate, all the other salts of which are insoluble.
It is a solution when you mix it enough so that the molecules of the alcohol fill the gaps of the water and so its turns homogeneous (looks the same throughout). But some alcohols don't because they might be more or less denser than water which prevents it from mixing together. Hope this helps =)
All types of combustions are exothermic.
No, since the ethanol is pure it is a base and will make the alluminium turn all black and rusty. Hope this helped :-)
It is impossible to make a saturated solution of ethanol or methanol and water because ethanol and methanol are completely miscible in all proportions. Some other alcohols may be less miscible and, if so, they could make a saturated solution. I will leave the question open with regards to ALL ALCOHOLS.
Distilled means that a liquid is separated from a mixture, and distilled vinegar is distilled from ethanol. All vinegar is made from this process, so there is no real difference. It is like saying 100% fruit juice is made from fruit.
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
To eliminate all foreign tastes and smells. The only thing you should taste or smell in unflavored vodka is ethanol.
None. Ethanol contains 7 calories per gram, but since ethanol is boiled off (distilled) from the sugary mash that creates it, there are no sugars or other carbohydrates left. This is not only true of ethanol, but all unflavored liquor. In fact, chronic alcoholics go through the same process of ketosis sought after by low-carb dieters; they're subsisting on ethanol calories and their blood sugar is near rock bottom.
By heating ethanol is evaporated and sugar remain as a solids.
Interesting question. I hope you know that vodka is primarily ethanol in water. All you have to do is find out the ph of ethanol. If you had some extra time you could marvel at the intersting qualities ethanol has when it interacts with organic material.
No. Ethanol is generally not considered an acid at all.
A VERY brief overview of the extraction process: Grind Ipomoea seeds. Soak grounds in nonpolar solution. Filter out (then throw out) bulk of liquid, evaporate remainder. Soak in polar solution (ethanol), throw out grounds, evaporate ethanol, and you have your product. Found this on a google search. There is a million ways listed, all involve alcohol, (ethanol).
The solute is generally an essential oil and the solvent is usually a low molecular weight alcohol like ethanol or methanol or isopropanol, possibly mixed with water.
Hypotonic actually stems from the early British invention of Tonic Water. Hypo, meaning "low," describes a Tonic Water that would have been stored on the bottom shelf. These were typically known to be of a lesser quality than the top shelf tonics, or "hyper" tonics. Therefore, hypotonic simply describes a lower quality solution, versus hypertonic, which describes a higher quality solution.
