Chem 17 ▪ General Chemistry Laboratory II Experiment 1 Calorimetry INTRODUCTION Chemical reactions are usually accompanied by the evolution (exothermic reaction) or absorption (endothermic reaction) of heat energy. When measured at constant pressure‚ the heat evolved (qp < 0) or absorbed (qp > 0) is equal to the enthalpy change‚ symbolized by ΔH. ΔH is positive for an endothermic process and negative for an exothermic one. If H f is the enthalpy of the final state and Hi of the initial state

This report demonstrates calorimetry‚ or the technique of measuring heat effects in the surroundings. In order to make sure that there is no temperature change‚ or that it is an isothermal heat transfer‚ it is kept at a similar temperature in an ice bath. By knowing the change in volume‚ the density of ice‚ and the density of liquid water‚ it is presumed that then you could decipher the mass of the ice that melted. With this‚ it is possible to understand the transfer of heat from this chemical equation

Experiment 1: Calorimetry INTRODUCTION In the calibration of the calorimeter‚ the net ionic equation used is H+(aq) + OH-(aq) H2O(l). The reaction released heat and is said to be exothermic. HCl is the limiting reactant of the reaction and o.oo5 moles of it was used. The heat generated by the reaction is 55.8 kJ. The sign of T of the reaction used for calibration is opposite to that of H. In the determination of heats of reaction‚ the reaction of 15 mL 1 M CuSO4 + 0.05 g Zn produced a

Part I The Dissolving of Solid Sodium Hydroxide in Water Procedure: 1. Measure out approximately 200 mL of distilled water and pour it into the calorimeter. Stir carefully with a thermometer until a constant temperature is reached. Record the volume of water and the constant initial temperature of the water on your data table.

1. Clean‚ rinse‚ and fill a buret with NaOH solution just as you did in last week’s experiment. Record the molarity of the NaOH and the initial NaOH volume reading from the buret (+0.02 mL). 2. Weigh an antacid table in a weighing boat and record the mass (+0.01 g). Transfer the tablet to a clean mortar and crush the tablet into a fine powder using the pestle. 3. Weigh about 0.2 grams (+0.01 g) of the ground up tablet powder and transfer it to a clean 250 mL Erlenmeyer flask. 4. Transfer

1. Start off by weighing two paracetamol tablets using some accurate scales. Record the mass down (1.15g). This had to be as accurate and precise as we could get it so we had the correct weight to start the experiment. Without this then the results we found at the end would not be accurate. A problem that could be faced with this is that the scales may not have been fully set to zero. Also it takes time for it to fully reach its weight on the reading so you may move them too quick before the right
