Crystallization of Supersaturated Sodium Acetate A supersaturated solution of sodium acetate is poured onto one small sodium acetate crystal. Crystals form from the liquid immediately upon contact with the seed crystal. A thermometer shows that the crystallization process is exothermic. A chemical hot pack is shown as an example of a commercially available supersaturated solution.
Solutions : FreezePtDepression (20 Variations) It takes 6.86 kg of ethylene glycol (antifreeze) to decrease the freezing point of 6.50 kg of water to -25.0oF (-31.7oC). How much sodium chloride (NaCl) would it take to decrease the freezing point of 6.50 kg of water to -25.0oF? (Assuming all the salt will dissolve in that amount of water.)
Determining the Pressure inside an Unopened Carbonated BeverageHans de Grys Determining the pressure of carbon dioxide inside a sealed soft drink can represents a challenging student exercise. Several methods are discussed for solving the problem, including applying the ideal gas law, gas collection via water displacement, and Henry's law. de Grys, Hans. J. Chem. Educ.2007, 84, 1117.
