Click the scoop to add salt to water and examine the temperature change. Reset the lab to select a new solute or amount and compare the temperature changes.
Students will be able to analyze energy changes that accompany chemical processes and classify them as exothermic or endothermic.
Endothermic and exothermic reactions have different uses. Some disposable heating pads utilize the energy change that occurs during the dissolution of calcium chloride, whereas instant cold packs often utilize the energy change that occurs during the dissolution of ammonium nitrate.
