Methanol will freeze at negative 143 (Fahrenheit)/ negative 97 (Celsius). If it is added to water (freezing point of 32*F/0*C) then it will make the water freeze at a lower temperature.

So yes, methanol will lower the freezing point of any liquid that freezes at a higher temperature than methanol. But methanol cannot lower the freezing point of any liquid that will still be liquid at -143*F/-97*C.

What will alcohol do to the freezing point of water?

No it would lower it. This is why de-icer is often alcohol (methanol) based. Alcohol turns to a solid (freezes) at a lower temperature then pure water. Freezing point of pure methanol is -98C


How much methonal is needed to lower freezing point of fresh water?

To lower the freezing point of fresh water by 1 degree Celsius, you need to add 1.86 grams of methanol per kilogram of water. The exact amount will depend on the desired degree of freezing point depression and the quantity of water.


What is methanols freezing point?

Methanol will freeze at -97 degrees celcius.


What is freezing point constant of methanol?

The freezing point constant of methanol is approximately -1.8 degrees Celsius per molal. This means that for every mole of solute added to one kilogram of solvent, the freezing point of the solution will decrease by 1.8 degrees Celsius.


What are the properties of a solution containing methanol in water?

A solution containing methanol in water is a homogeneous mixture where methanol is dissolved in water. Methanol is miscible in water, meaning it can mix evenly with water at any proportion. This solution has a lower freezing point and higher boiling point compared to pure water. It is also flammable and toxic if ingested in large quantities.


Is the freezing point of ice cream lower or higher than the freezing point of water?

It is lower.


Which has the lower freezing point oxygen or ethanol?

Oxygen has a lower point.


Best jet fuel freezing point depressant?

One effective jet fuel freezing point depressant is Diethylene glycol monomethyl ether (DiEGME). It is commonly used in aircraft fuels to lower the pour point and prevent freezing at high altitudes. Other additives such as ethylene glycol and methanol can also be used as freezing point depressants for jet fuel.


Why methanol uses as brine?

Methanol is used in brine solutions because it lowers the freezing point of the solution, making it effective in preventing freezing and maintaining fluidity in low-temperature environments. This is especially useful in applications such as de-icing fluids for aircraft or as an antifreeze in pipelines and equipment operating in cold climates.


Why do race cars use methanol?

methanol has a lower burning point, so an engine running on methanol can make more power with less heat.


What information is most useful to determine the solution that has a lower freezing point?

To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.


Can methanol melt ice?

in fact yes.....methanol melt ice as we use methanol to remove the ice formed around some valves "JT valves" in industry..but i dont know how it works yet
