- The freezing point of methanol depends on its concentration in water.
- For example for 10% methanol by mass in water, the freezing point is -7 degree centigrade. For 100% methanol by mass, the freezing point is -98 degree centigrade.

Does methanol lower the freezing point?
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 is oxygen's freezing point?
oxygen's freezing point is 222.65 degrees Celsius
Which alcohol has a boiling point closest to that of hexane?
Methanol
What is the cerium freezing point?
Cerium's freezing point or the melting point is 795 oC.
What does salt have to do with the freezing point of water?
Adding salt to water the freezing point decrease.

Why methanol uses as brine?
Coz, methanol reduces the freezing point of the mixture to under -30o C
Can the freezing point be lower than its boiling point in a constant pressure?
At a constant pressure, the freezing point is always going to be lower than the boiling point.
What is methanols freezing point?
Methanol will freeze at -97 degrees celcius.
What is the freezing point depression constant for naphthalene?
The freezing point depression constant for Naphthalene is 6.9 degrees Celsius/mhttp://en.wikipedia.org/wiki/Freezing-point_depression
What is the molar freezing point constant?
molal
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
What temperature does liquid methanol turn to gas?
Pure Methanol has a freezing point of -97.7oC.
The freezing point and boiling point for matter is a constant Explain this meaning of constant?
It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.
The solution has a freezing point of -2.79 . The freezing point depression constant for water is 1.86 K m-1. What is the nitrate concentration in the solution?
The solution has a freezing point of 2.79 and this is the frezzing point of mercury
Constant freezing point of acetone?
The freezing point of acetone at sea level is -94.7 C, -138.46 F, 178.45 k.
What is the trend for freezing point?
The freezing point of a given substance, under constant pressured does not change so there is no trend.
