Guidelines for Discussion: Answer the following questions, as per your experimental observations. 1. What happens if initial temperature is not recorded in each experiment? 2. What happens if the calorimeter is not covered properly? 3. How will you get the final temperature? 4. What are the techniques used in this experiment? 5. Comment on possible accuracy of your results Guidelines for Conclusion: 1. What is your result considering the objective (s) of the experiment? 2. What did you learned in this experiment? Lab Assignment: 1. Define Exothermic and Endothermic reaction. Clasify the above experiments as exothermic or endothermic. 2. When you draw the graph for the third experiment, why did the curve graph go down? 3. When is the lattice energy for salt greater than that of Hydration energy during the dissolution of salt in water? Is this reaction endothermic or exothermic?
