Question
You are asked to prepare a temperature bath that freezes at –12.5 °C using only water and ammonium sulfate. Kf for water is 1.86 °C/m and Kb for water is 0.51 °C/m. The normal freezing point is 0.00 °C and the normal boiling point is 100.0 °C. Use 132.14 g/mol as the molar mass for ammonium sulfate.
a. Name the three colligative properties discussed in class and write the mathematical expressions that describe each.
b. Calculate how many g of ammonium sulfate you would need to prepare this temperature bath which freezes at –12.5 °C if you use 500. g of water.
