Purpose The purpose of this experiment is to, using a calorimeter, measure the energy changes accompanying neutralizing reactions. Introduction We will take a premade calorimeter (2 styrofoam cups with a piece of cardboard with a hole in the center) and first add 50 mL of cold water. We will heat up 50 mL of water in a separate beaker to approximately 50˚C. The temperature of the cold water will be measured, then with the thermometer still in the cold water, the warm water will be added. All temperatures will be recorded and the heat capacity of the calorimeter will be measured by the formula demonstrated under the discussion area. The thermometer and calorimeter then will be washed and dried. 50 mL of NaOH is then to be added to the calorimeter. The temperature is then to be recorded. Then 50 mL of HCl is added to the NaOH and the highest temperature is recorded. The total joules released by the reaction is then to be calculated by using the formula under the
