Azat Posted April 27, 2004 Report Share Posted April 27, 2004 At what temperature does 40% Alcohol freeze. I was at a friends house recently who took out a bottle of Grey Goose from his freezer and it was solid ice and we had to wait for about half an hour before we could pour some vodka slushes and drink them. So my question is does anyone know the freezing point or the math for calculating the freezing point for alcohol based on % Quote Link to comment Share on other sites More sharing options...
DominO123 Posted April 27, 2004 Report Share Posted April 27, 2004 At what temperature does 40% Alcohol freeze. I was at a friends house recently who took out a bottle of Grey Goose from his freezer and it was solid ice and we had to wait for about half an hour before we could pour some vodka slushes and drink them. So my question is does anyone know the freezing point or the math for calculating the freezing point for alcohol based on % There is a way to calculate it. First, if it is a v/v % you take alcohol density and from it you calculate the mass(in proporition) of the alcohol. And from it you calculate the grammes per moles(by using the ethyl-alcohol chimical formula (CH 3 CH 2 OH)). After you calculate it you divide it from the mass of the alcohol to find the numbers of moles of alcohol. Be x, the mole of alcohol you found. Be y, the mass of water in Kg(you calculate it by using the 60% v/v and its density, since the density is 1 in this cases, it is 0.6 Kg) Devide x/y You multiply what you found by waters freezing depressing constant (-1.86) and you have the answer for what you were searching. The problem is that I forgot if drinks alcohol concentration is v/v, if it is m/v, m/m, tell me I will modify a little bit that thing. Right now, I am a little too lazzy to calculate it myself. But if you do what I said, it'll work. Quote Link to comment Share on other sites More sharing options...
Azat Posted April 27, 2004 Author Report Share Posted April 27, 2004 Sip, can you please read what Domino wrote and translate it so I can understand what I am suppose to do? The only moles I know about is this one http://armenians.com/forum/index.php?showt...360entry81496 Quote Link to comment Share on other sites More sharing options...
vava Posted April 27, 2004 Report Share Posted April 27, 2004 Depends on the purity of the alcohol used (Domino's calculation is pretty much correct, if i remember anything from biology courses), but for a short answer: Most alcolohol at 40% should not freeze until roughly -20 degrees celsius. I figure your friends teenage son had been dipping into the Grey Goose (and adding water to cover up ) Quote Link to comment Share on other sites More sharing options...

Here I have found a link for you. http://www.newton.dep.anl.gov/askasci/chem00/chem00924.htm It is with isopropyl and not ethyl, so you just have to replace 60g by 46 g... and it is a m/m % on the example.

Sip jan, I really was not kidding, I just said that to make Domino feel better. Can you please explain. Quote Link to comment Share on other sites More sharing options...
