Thermochemistry: An Ice Calorimeter Determination of

Effect Enthalpy


In CHM151 you learned about the initial law of thermodynamics, the statement that energy may be transferred (as heat or perhaps work) between a system as well as the surroundings, but energy is neither developed nor ruined. This legislation is the base for calorimetry, the technique of calculating heat results in the natural environment to gain insight into energy transactions to or from a process of interest.

In the typical calorimeter, we all measure heat-induced temperature changes. In fact , temperature is sometimes defined as the type of energy transfer due to temperature variations between system and surroundings. In today's research laboratory, by contrast, the heat transfer takes place with no temperatures change–it is definitely an isothermal heat transfer. Consider the 2nd law because you think about what hard drives this temperature transfer.


Background studying

Examine and completely understand this portion of the lab manual and the Thermodynamics chapters in the lecture book.

Organizing the lab notebook computer

Set a brief outline of the prepared experimental procedure in your notebook. Include the unsafe properties of lab chemical substances.

Keep space to record significant experimental specifics, such as the stock reagent concentrations (taken in the stock-bottle labels), descriptions with the instruments applied, and the names of your co workers. Prepare a stand that will allow you to record the necessary data, such as pipet blood pressure measurements and ice-bath temperature readings as a function of time. Read the pipet to 0. 001-mL precision, look at the thermometer to 0. 1 В°C accuracy, and record time to the nearest second.



Test the calorimeter device set-up before running the experiment. A.
