Cooper 106). None of our experiments used pure, distilled water. For convenience, our team utilized tap water, which is water mixed with various minerals and impurities, to conduct all of the experiments. Therefore, our results are not as accurate as they could have been, but under the time restrictions we were placed under, they are good approximations. ConclusionAfter all of the experiments and calculations were concluded, the team was able to come to tentative assumptions. The data suggests that the salts (used in the salt and water reactions) were endothermic because they absorbed heat from the surroundings. The acid and base reactions, on the other hand, were exothermic because they released heatduring the reaction. By comparing the strong acid and base reactions to the weak acid and base reactions, it can be determined that the strong acids and bases gave off more heat. It was also resolved that the concentrations of the acid and bases did effect the amount of heat that was released. It seemed that by increasing the concentration used in the reaction it caused the reaction to release more heat.Experimental ProceduresCalorimeter Construction: 1.Two Styrofoam cups were obtained2.A sheet of aluminum was wrapped around one of cups 3.The cup with the aluminum wrapping was placed inside the other cup4.A square piece of cardboard was cut to function as the lid5.A hole was poked through the cardboard to allow the insertion of the thermometer 6.The structure was labeled calorimeter one or two with a black marker; so the two different vessels would not be confused during the experiments7.Then a second calorimeter was constructed using the same steps as seen aboveFinding the Heat Capacity of Each Calorimeter:1.50 mL of water were measured using a graduated cylinder and put into a calorimeter2.The temperature was recorded every 30 seconds using the thermometer. This was done for two to five minutes to make sure the temperature had...
