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 freezing point depression constant for water?
The freezing point depression constant for water is 1.86 degrees Celsius per molal.
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.
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.
What is the freezing point depression constant for water and how does it affect the freezing point of water?
The freezing point depression constant for water is 1.86 degrees Celsius per molal. This means that for every mole of solute added to water, the freezing point of water decreases by 1.86 degrees Celsius. The presence of solute particles disrupts the formation of ice crystals, lowering the freezing point of the solution compared to pure water.
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 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 are the freezing point depression equations used to calculate the change in freezing point of a solution?
The freezing point depression equation is Tf i Kf m, where Tf is the change in freezing point, i is the van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution.
Molar mass by freezing point depression chemistry lab?
In a molar mass by freezing point depression lab, a known quantity of solute is added to a solvent, resulting in a lowered freezing point. By measuring the change in freezing point and knowing the constant for the solvent, the molar mass of the solute can be determined using the formula: ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the cryoscopic constant, and m is the molality of the solution.
Why is the temp of boiling pure acetone constant?
Acetone has a constant boiling point because it is an azeotrope. Azeotropes are mixtures of two or more liquids whose proportions cannot be altered by simple distillation. They are also called constant boiling mixtures.
What are the freezing point depression constants and how do they affect the freezing point of a solution?
Freezing point depression constants are specific values that depend on the solvent being used. They represent how much the freezing point of a solvent will decrease when a solute is added. The higher the constant, the greater the decrease in freezing point. This means that adding a solute to a solvent will lower the freezing point of the solution compared to the pure solvent.
What would the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C
