Freezing Point Of Egg Experiment
Record the freezing point of the pure water and the freezing point of the salt solution.
The freezing point of the pure water is 0 degrees Celsius. (not in this data, the freezing point is -2)
The freezing point of the salt solution is -1.
C. How do these two freezing points compare? If there was no experimental error in this lab, the freezing point of the salt solution would be lower than that of the pure water. In this case it is the opposite due to error.
D. What are some practical applications of freezing point depression, boiling point elevation, and vapor pressure lowering? An example of freezing point depression is when one adds anti-freeze to car fuel to prevent the fuel from freezing in cold temperatures, like we are experiencing in the north east region now. An example of boiling point elevation would be the same. The antifreeze in the car also elevated the temperature of the fuel preventing your car from overheating. An example of vapor pressure lowering would be freeze drying. Freezing occurs because the vapor pressure from the surrounding air is lowered, and causes the substance to freeze.
