Ammonium Sulfate Solution (A5479) Bulletin

The saturation concentration of an ammonium sulfate solution is temperature dependent. Lower temperatures will decrease the concentration at which the solution is saturated. A saturated solution of ammonium sulfate is 4.1 M at 25 °C, but is 3.8 M at 0 °C, the difference in molarity being 7%. Accordingly, a saturation table

3.5.1 Thermodynamics Enthalpy change (ΔH) of solution

(specific heat capacity of the solution = 4.2 kJ kg-1 ºC-1) Energy change in the water = mass x specific heat capacity x temperature change. Energy change = 0.1 x 4.2 x 7. Energy change = +2.94 kJ (the sign is positive because the water temperature decreases, i.e. heat is being transferred from the water to the ammonium nitrate it is an endothermic change) Moles of ammonium nitrate = 10/80 = 0.125 moles

1. Prepare saturated solution of Ammonium Sulfate, for example ~550g made up to 1L distilled water. Heat gently to dissolve all the Ammonium Sulphate and let cool to working temperature on a magnetic stirrer. Crystals of ammonium sulfate should form and will tell you that the solution is fully saturated. 2. Add either the appropriate volume of saturated Ammonium Sulfate or solid Ammonium Sulfate to your

Chemistry: Ammonium Nitrate Heat of Solution

07/03/2007  The mass of the solution is the sum of the masses of the water and ammonium nitrate originally placed in the calorimeter. The specific heat capacity of the aqueous solution is usually close to that of pure water (4.184 J oC-1 g-1). The objective of this experiment is to determine the heat of reaction (in this case a heat of solution). The above equations can be combined and rearranged to yield a
