What is the freezing point of isopropyl alcohol?

Oct 15 2006Melting point -89 C (185 K) Boiling point 82 3 C (355 K) The above assumes that the alcohol being used is 100 % pure Actually it is not easy to purchase 100 % isopropyl alcohol because what's available in the drugstore contains water that must be factored into the calculation

Freezing Point Depression Flashcards

In the freezing point depression lab what was used to lower the freezing point of a water/ice/rock salt solution? isopropyl alcohol Colligative properties are dependent on what? Quantity over quality (number of solute particles vs identity of solute particles) Besides freezing point depression what are some other examples of colligative properties? osmotic pressure and boiling point

will water mixed with rubbing alcohol freeze? : askscience

Isopropyl alcohol freezes at -88degC /u/NDaveT 80 proof vodka will freeze at about -27degC 100 proof vodka will freeze at about -40degC Solutions of isopropyl alcohol and water will have a different (higher) freezing point than the one I gave for isopropyl alcohol neat but the point is that it will depress the freezing point enough to be able to clean your windshield of frost/ice

How is the freezing point of water affected by Salt Sugar

2009-04-30I tried this chemistry expirament and I could not get it to work right so if anyone can help me I would appreciate it I have Ice 120 mL of water and 30 grams of Salt Sugar and 43 mL of 70 percent isopropyl alcohol in 3 cups I need to obtain the freezing point with my thermometer I know the temperatures are suppose to go down but for me they all average at 4 degrees C which is not right

How much isopropyl alcohol is needed to keep water from

Doesn't matter if you want to use mass or volume You see isopropyl alcohol (IPA) does NOT stop water from freezing It only lowers the freezing temperature So if you have ANY water in the mixture the temperature can be lowered sufficient
