I did a lab in which I dissolved sodium bicarbonate and sodium acetate in water, using a simple styrofoam cup as a calorimeter. For sodium bicarbonate, the temperature decreased from 20.8 degrees Celsius to 16.6 degrees Celsius. For sodium acetate, the temperature decreased from 18.4 degrees Celsius to 17.5 degrees Celsius. I used 150 mL of water to dissolve sodium bicarbonate, and 32.5 mL of water to dissolve sodium acetate. I used 15 grams of sodium bicarbonate and 3.25 grams of sodium acetate. I calculated that -2.64 kJ was released in the reaction for sodium bicarbonate, and -0.122 kJ was released in the reaction for sodium acetate. I also calculated that 0.18 moles of sodium bicarbonate were used and 0.0396 moles of sodium acetate was used. I then got -14.67 kJ/mol as the molar heat of solution for sodium bicarbonate, and -3.08 kJ/mol for the molar heat of solution for sodium acetate. However, when I calculate the percent errors, I am getting numbers of over 100. Did I do…
