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 would the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C
Will methanol melt ice?
It depends on the temperature of the methanol. If the methanol is warmer than 32F (0C) it will melt the ice until the methanol reaches 32. Methanol can be less than 32F and still liquid in which case it won't melt the ice. It's about heat transfer not material.
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

-5.58 C
What is methanols freezing point?
Methanol will freeze at -97 degrees celcius.

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 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?
The molar freezing point constant (Kf) is a physical constant that represents the amount by which the freezing point of a solvent is lowered for each mole of solute dissolved in it. It is specific to each solvent and is used in calculating the freezing point depression in colligative properties.
What is the freezing point depression constant for water?
The freezing point depression constant for water is 1.86 degrees Celsius per molal.
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.
What is the significance of the freezing point depression constant in determining the freezing point of a solution?
The freezing point depression constant helps determine how much the freezing point of a solution will decrease compared to the pure solvent. This is important because it allows us to calculate the exact freezing point of a solution, which is useful in various scientific and industrial applications.
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.
Constant freezing point of acetone?
The freezing point of acetone at sea level is -94.7 C, -138.46 F, 178.45 k.
How can the freezing point depression method be used to calculate the molar mass of a solute in a solution?
The freezing point depression method can be used to calculate the molar mass of a solute in a solution by measuring the decrease in the freezing point of the solvent when the solute is added. By knowing the freezing point depression constant of the solvent and the amount of solute added, the molar mass of the solute can be calculated using the formula: molar mass (freezing point depression constant molality) / freezing point depression.
