Experiment: Calorimetry Laboratory Experiment – Heat of Solution Aim: The aim was to use calorimetric measurements to calculate the molar heat of solution of NaOH and NH4NO3. Method: 1. 50g of water was poured into a clean polystyrene calorimeter (Styrofoam cup) and the initial temperature was measured. 2. A teaspoon of 2g of the selected salt was measured and added into the water. 3. The solution was stirred and the final temperature was measured when the solution stabilised and the results

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

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
