Ice Calorimeter Determination with Mg
Ice Calorimeter Determination with Mg June 18th 2013

Abstract: This experiment determines the amount of energy needed to melt ice. A spontaneous increase in enthalpy produce by combining 0.2036g Mg and 5.00mL H₂SO₄, ice was melted and readings were taken by using an ice calorimeter. Readings were taken before during and after the reaction were completed. The data taken shows a value of -405 KJ/mol while the theoretical value was -483.7 KJ/mol. Calculating the experimental value taken with the actual theoretical value it shows a 16% error in the experiment. A possible explanation for this error could be due to heat escaping the open test tube during the Mg reacting with H₂SO₄. Data: Table 1 The fall of H₂O in the Ice Calorimeter Time (s) | Volume (mL) | 0.0 | 9.00 | 30.0 | 8.89 | 60.0 | 8.85 | 90.0 | 8.80 | 120.0 | 8.78 | 150.0 | 8.75 | 180.0 | 8.73 | 210.0 | 8.73 | 240.0 | 8.71 | 270.0 | 8.69 | 300.0 | 8.67 | Table 2 The decrease in H₂O in the ice calorimeter during the Reaction Enthalpy of Mg and H₂SO₄ Time (s) | Volume (mL) | 330.0 | 8.50 | 360.0 | 8.30 | 390.0 | 7.50 | 420.0 | 6.72 | 450.0 | 6.00 | 480.0 | 5.45 | 510.0 | 5.07 | 540.0 | 4.63 | 570.0 | 4.35 | 600.0 | 4.05 | 630.0 | 3.83 | 660.0 | 3.60 | 690.0 | 3.40 | 720.0 | 3.27 | 750.0 | 3.15 | 780.0 | 3.03 | 810.0 | 2.95 | 840.0 | 2.87 | 870.0 | 2.81 | 900.0 | 2.75 | 930.0 | 2.70 | 960.0 | 2.66 | 990.0 | 2.57 | 1020.0 | 2.51 | 1050.0 | 2.48 | 1080.0 | 2.45 | 1110.0 | 2.40 | 1140.0 | 2.38 | 1170.0 | 2.35 | 1200.0 | 2.32 | 1230.0 | 2.30 |

    The purpose of this lab is to determine an accurate time when the ice completely melts and the water starts to boil. The problem is which type of temperature change will result from heating ice to liquid, then boil (steam)? What will happen to the water after the boil? I hypothesise the water heats ice to liquid and then goes to simmer and boil. The independent variable is the hot plate changed to a burner itself. The dependent variable is what we are measuring is the time.…

    All chemical reactions are processed through energy exchanges. Chemical reactions either absorb energy or release energy into their surroundings. In thermodynamics, endothermic reactions absorb energy where exothermic reactions release energy. In this experiment, we will be observing the chemical reactions that occur when a specific liquid is combined with a specific solid. We will measure the temperature of the liquid before the solid is added. Then we will measure the temperature of the liquid after the solid is added. We, then, will record the results, graph the temperature changes if any, and draw a conclusion whether the reaction is endothermic or exothermic reaction.…
