When a solute is dissolved in a solvent, the freezing temperature is lowered in proportion to the number of moles of solute added. This property, known as freezing-point depression, is a colligative property; that is, it depends on the ratio of solute and solvent particles, not on the nature of the substance itself. The equation that shows this relationship is where Δt is the freezing point ...melting points. g. Stir the contents of the test tube gently, using the thermometer. Record the temperature at which the last crystal has melted. This is the melting point (NOTE: this is the same as the freezing point). h. Repeat this process once for each test tube. The measured freezing points should agree within +/- 0.3 °C. 7.Sea water becomes more and more dense as it becomes colder, right down to its freezing point. Fresh water, on the other hand, is most dense while still at 39.2 degrees Fahrenheit, well above the freezing point.
