I know this answer i was wondering if any of you know how cold it need to be to freeze 40% alcohol?

Question

Just wondering strength is 40% and the volume is a normal bottle of vodka good luck and thank you

hailee is the closets people and hopefully we will get a brainbox on here tonight

okay people i am sorry i should of gave your more facts
400grams of alchol and 600 grammes of pure water.

bill you were right but i decided to add quantities.The answer is 30.99c or -24f

Answer 1

(-29) degrees Celsius or -20.2 degrees Fahrenheit

Answer 2

What will happen is that some of the water will freeze first, which will make the free alcohol content stronger. If you can get the temperature low enough, eventually it will all become solid but you will have crystals of ice embedded in solid alcohol, which may still not be 100%, so the freezing point will almost certainly be different from that quoted for pure ethanol.

I have a bottle of vodka in the freezer at the moment, in which I steeped a good quantity of scotch bonnet chillis. I think the liquid reduced to about half when I froze it and filtered out the ice, so I should have something around 75% - 80% alcohol now! In the freezer which I think is around -10C, it has a syrupy consistency, so is probably not far off freezing.

Believe me, you do not want more than about a teaspoonful to blow your eyes out, with that stuff!

Edit: While Libby and Hailee D get all technical, I can tell you that some water freezes first, so those calculations will need modifying!

Answer 3

80 proof vodka will freeze at approximately -26.95C or -16.51F. 100 proo
It's freezing point depression, the formula is Delta T = K(sub F)m where Delta T is the change in freezing point, Kf is a constant (-1.86m/C for H2O), and m is the molality of the soln.

If you want to calculate the freezing point of Vodka go through the following exercise.

Assume 1000g of soln, we'll use 80 proof in this example, 40% ethyl alcohol (CH3OH) and 60% H2O. That means we'll have 400g of CH3OH and 600g (0.6kg) H2O.

First, obtain the number of moles of CH3OH in the soln to determine molaity. CH3OH has a molar mass of 46.7g/mol.

(Mass CH3OH) / (Molecular Weight CH3OH) = moles CH3OH

(400g CH3OH) / (46.7g/mol CH3OH) = 8.57 mol CH3OH

Next calculate the molality of the soln.

(Moles Solute) / (Mass Solvent) = Molaity

(8.57 mol CH3OH ) / (0.6kg H2OH) = 14.28m

Now, plug into the freezing point depression equation.

Delta T = K(sub F)m

Delta T = (-1.86m/C)(14.28m) = -26.56C

Therefore a soln of 40% ethyl alcohol and 60% water would have a feezing point of 0C + (-26.56C) = -26.56C

To convert to F use, C = (F-32) * ( 5/9) or F = -15.81F



f vodka will freeze at approximately -40.43C or -40.78F (

Answer 4

Ethyl Alcohol -- 117

Answer 5

I've made daiquiri cubes before in reg. frig. freezer. My neighbor keeps a bottle of Sky Vodka in his, to keep it fresh tasting. So my answer is.....I don't know! How cold does it have to be?

Answer 6

95% ethanol (Everclear, if you like) freezes at about -110°C, which is about -200°F. Assuming a linear relationship we estimate that 40% ethanol freezes a bit below -40°C = -40°F.

Answer 7

I honestly cant see ANY advantage to this - rice only takes 12-14mins to cook, why bother?

Answer 8

-46.32 Degrees C

Answer 9

i dont think it would freeze because of the alcohol

Answer 10

yes I do
