1 312 Part B: Quantitative Analysis of the Dissolution of Magnesium Sulfate 5 Graph your time/temperature data by hand (as instructed) for all four experimental runs in Part B using the graph paper provided. You will be producing FOUR graphs. Label your axes, include units, title your graphs "Temperature vs Time" and scale your graphs appropriately (See the Graphing Study Aid). Indicate the initial temperature and final temperature on each of the four graphs. The final draft of all graphs should be in pen. Indicate initial and final temperatures on your graphs. **Remember that you are looking for the intersection of two lines when plotting your final temperature. The point of creating this graph is to determine your FINAL TEMPERATURES for each reaction. 6 Calculate the difference in temperature (AT) for each of the four runs in Part B. Show work. T -1 7 Calculate the heat of solution for each of the four dissolution reactions using the equation. **Since our reac- tion was conducted at a constant pressure (p), we can assume that q = AHsoln AJAH yon - 9 - mx CX AT 4,184xs -T:) 3 - Y 100 nl von (Assume that the density of your solution is 1.000 g/mL and its specific heat is the same as water) 8 Calculate the heat of solution per mole of magnesium sulfate dissolved for each of your results in question #7. Calculate the average heat of reaction (AHsoin/mol solute). 9 Using a thermodynamic table and AH values, calculate the theoretical AHsoin for the dissolution for magnesium sulfate. 10 a) Calculate the % error between your experimental AH in and the theoretical value. b) Comment on (1) the magnitude of your error and (II) its possible causes.

Answer #1

solution Ti = 21.80 Tf= 28.41 AT = Tf - Ti AT = 28:41 - 21180 AT = 6.61°C]
