Question

Why is it necessary to dry the ice before adding it to the warm water?

1 of 2
Molar Heat of Fusion
Object:
In this experiment, you will determine the change in temperature of a mixture of warm
water and ice. From this data, the amount of heat absorbed by the ice can be determined
and ultimately, the molar heat of fusion of ice calculated.
Procedure:
1.
Obtain mass of styrofoam cup.
2.
Add 150 g of warm water (~ 30 °C).
3.
Obtain mass of cup plus water.
Stir the water with thermometer and determine the temperature to the nearest tenth
of a degree.
4.
Dry 1 ice cube with a paper towel to remove any water, and place the ice
immediately in the cup; do not splash any water from the cup.
5.
Stir quickly until all the ice is melted, then record the temperature to the nearest
tenth of a degree.
6.
7.
Determine the mass of the cup and water.

Suppose a group of students tell you that they added solid sodium chloride NaCls to 35 mL of deionized water and they did not record how many grams of NaCl they added but they got a freezing point depression of 1.25°C. Calculate how many grams of NaCl the students added. The pure freezing point of water is 0.00°C and the freezing point depression constant (K) of water is 1.858 °C/m. Remember that NaCl is a solid salt and an ionic compound therefore it contributes a negligible amount to the overall additive volume and keep track of its van't Hoff factor. The density of water at 20°C is 0.9982 g/mL.
