Analytical Chemistry


What is calorimetry and what is it used for?

Calorimetry involves measuring the amount of energy released during a chemical reaction in the form of heat. This is accomplished using a device called a calorimeter. A calorimeter is a container inside which a chemical reaction can be carried out while thermally insulated from the surroundings. This can even be something as simple as a sealed Styrofoam® coffee cup with a thermometer inserted through the lid (though more sophisticated devices certainly do exist). The temperature change inside the calorimeter can be monitored to determine the amount of energy given off during the chemical reaction, which can then be used to determine the enthalpy change associated with the reaction.
