What is the source of error in freezing point depression lab?
An error could have been the time allowed waiting for the water and solution to freeze. The solutions did not sit long enough to get the final temperature of the freezing point, and if the final freezing point was obtained, then the calculation would have been more accurate.What are the factors affecting freezing point depression?
The factors affecting the freezing point are given below.
Intermolecular forces: If the intermolecular forces are high, then the freezing point is also high. If the forces are weak then the freezing point is low.Pressure: With the increase in pressure, the freezing point also increases.What are the misconceptions about freezing point depression?
Their misconception is assuming that freezing point depression of solution occurs due to blocNing solutes to the surface of the solution thus preventing the solvent particles from forming a crystal lattice so that the freezing point decreases.- CONCLUSION. In conclusion, freezing point can be determined when the temperature of liquid and solid are at equilibrium, so that their vapour pressure is equal. The vapour pressure of solution can be lower than pure solvent when a non-volatile solute is added into volatile liquid solvent.
