In my chemistry lab course, we did a calorimetry lab to determine which salts make the best hot and cold packs.
In my chemistry lab course, we did a calorimetry lab to determine which salts make the best hot and cold packs. We dissolved different salts in water, recorded the increase or decrease in the temperature of the water, and then determined qrxn and delta H. The most exothermic salts made the best hot packs, and the most endothermic salts made the best cold packs. The below question is asking for other ways to do the experiment and how to further analyze results:
What is the error you encountered? These labs are not perfect, nor are they designed to be, so remember, adding more trials or correcting human error should not be the only thing that you would change. Are there other techniques you could use? How would you further your analysis?
