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
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
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.
The change in the freezing point of a solvent by the addition of a solute is called?
freezing point depression ..
What is the approximate freezing point depression of a 0.050 m aqueous solution?
-0.37 C
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.
How does changing the concentration of a solution affect the kf?
Increasing the concentration of a solute the freezing point depression is increased.
What general statement can you make concerning the relationship between the number of moles of solute and the magnitude of the freezing point depression?
Increasing the concentration of the solute the freezing point decrease.

What happens when freezing H2O and NaCl?
The freezing point of the solution depends on the NaCl concentration.
Does sugar the time it takes water to freeze?
The freezing point of solution is always less than that of the freezing point of the pure solvent. The freezing point of pure water is 0 (zero) degree celsius. The freezing point of the water decreases with the increase in the sugar concentration. for ex. a 10 grams of sugar when dissolved in 100 grams of water, the freezing point depression of -0.56 degree Celsius A 10 molal sucrose will bring about the depression in freezing point of water to about -20 degree celsius
