Purpose : The purpose of this experiment is to find out if a reaction is exothermic or endothermic. This is done by using a calorimeter and by measuring the surrounding temperature of a specific reaction. We figure this out by the change in temperature. If the change in temperature is positive it is exothermic and if the change is negative the reaction is endothermic. Procedure : 2.0 M of NaOH was put into a styrofoam cup. 5 mL of 2.0 M HCl was then put into a graduated cylinder, swirled, and dumped into waste beaker. The process was then repeated. 50 mL of 2.0 M HCl was then put into a graduated cylinder, and the exact volume was recorded. 30 second increments were for 3 minutes to measure the temperature of NaOH. The NaOH was added to HCl and the temperature was recorded for 5 minutes. 50 mL of distilled water was put into a styrofoam cup. 5 mL of 2.0 M NaOH was put into a graduated cylinder, swirled, and dumped into a waste beaker. The process was then repeated. About 50 mL of 2.0 M NaOH was put into a graduated cylinder, and the exact volume was recorded. 30 second increments were used for 3 minutes to measured temperature of water. NaOH was put into water and the temperature was taken for 5 minutes. 50 mL of distilled water was put into a styrofoam cup. 5 mL of 2.0 M HCl was put into graduated cylinder, swirled, and dumped into waste beaker. This process was then repeated. About 50 mL of 2.0 M HCl was put into a graduated cylinder, and exact volume was recorded. 30 second
