∙ 10y agoFreezing point depression isn't a medical term, but a physical process where adding solvents to solutes reduces the freezing point. An example, familiar to all of us, is adding salt to water, such as when we spread rock salt on the road in winter to stop ice forming on them.

The freezing point of a solution containing 4.12 g of unknown solute in 100 grams of camphor is 166.2 degrees C what is the freezing point depression?
f.p depression = (freezing point of pure solvent)-(freezing point of solution) -------> 178.4-166.2=12.2
What kind of salt to use on sidewalks for snow?
Salt works by lowering the melting or freezing point of water. The effect is termed 'freezing point depression'.
Why do we salt roads?
Salt will reduce the freezing point of water to below 32ºF, thus making it less likely to have slippery roads when temperatures are near the freezing point. This happens because of the colligative property of freezing point depression.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
What temperature is the freezing temperature outside?
32 F, 0 C, 273.15 Kelvin. At STP, pure water freezes at the above temperatures. Note that adding some solute (such as table salt or ethanol) will lower the freezing point (see Freezing Point Depression).
What does the depression of the freezing point dependent on?
The depression of the freezing point is dependent on the nature of solvent and concentration of solute.
What is the tendency of a solute to change the melting point of a solid called?
The answer is "Freezing point depression" on Apex
The change in the freezing point of a solvent by the addition of a solute is called?
freezing point depression ..
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
The freezing point of a solution containing 4.12 g of unknown solute in 100 grams of camphor is 166.2 degrees C what is the freezing point depression?
f.p depression = (freezing point of pure solvent)-(freezing point of solution) -------> 178.4-166.2=12.2
Could freezing point depression be used for substances that are not soluble in water?
Substances which are insoluble in a given solvent do not cause a freezing point depression in that solvent.
What are examples of freezing point depression boiling point elevation and vapor point lowering?
The freezing is ag gago weak
What is the freezing point depression of sodium chloride?
The maximal freezing point depression for sodium chloride is -18 0C. For the theoretical calculus see the link below.
Why is the curve for the freezing point of solvent different from the freezing point of solution?
it is increased with the increasing density
How are freezing point depression and boiling point elevation useful?
the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.
Why does the freezing point decrease when naphthalene is added in camphor?
When adding a solute to a solvent, the freezing point decreases and is also known as freezing-point depression. Hence when naphthalene is added to camphor the freezing point decreases.
What is the approximate freezing point depression of a 0.050 m aqueous solution?
-0.37 C
