Your discussion should contain at least 3 paragraphs, one for each of the experimental parts. You may choose to have one additional paragraph which either explains what you will be writing, which summarizes what you wrote or
which ties the 3 parts of the experiment together. Your discussion for each part of the experiment should focus
on explaining your results, interpreting your results and discussing whether they are reasonable (remember to
use context for example, literature values for any results you have calculated). Observations should be used to
interpret what is happening chemically. (For example, instead of stating, The temperature in the calorimeter
decreased (an observation), it is better to explain by stating, The solution absorbed energy during the dissolution
as the temperature in the calorimeter decreased.)
When writing your discussion, you should consider the following questions and make sure that your answer is
incorporated into your discussion seamlessly (in other words, please do not number your responses or put them
in separate paragraphs).
1. What sort of value do you expect to obtain for the enthalpy of neutralization of a strong acid and a strong base? How can you tell if your value is reasonable? Would you expect to obtain the same value
if a different strong acid or strong base was used in the reaction? Why? Can you find a literature value
with which you can compare your experimental result? Do you expect the values for different trials for
the same experiment to give you different values? What do your results show?
2. What sort of value do you expect to obtain for the enthalpy of dissolution of a salt? What factors might
affect the value of the enthalpy of dissolution? Can you find a literature value with which you can
compare your experimental result?
3. What sort of value do you expect to obtain for the specific heat capacity of your metal? Why? Is the
value you obtained reasonable? Why? Can you find a literature value with which you can compare your
experimental result? Do you expect the values for different trials for the same experiment to give you
different values? What do your results show?
4. What do the 3 parts of this experiment have in common? What is the chemical concept that relates
to them? How does this technique work? Are the results obtained using this technique scientifically
accurate/precise? How do you know?
