How to calculate heat of solution
WebAbstract. In solution calorimetry the heat of solution (Delta (sol)H) is recorded as a solute (usually a solid) dissolves in an excess of solvent. Such measurements are valuable during all the phases of pharmaceutical formulation and the number of applications of the technique is growing. For instance, solution calorimetry is extremely useful ... WebWhat is the heat of solution of NaCl? So, when 1 mole of sodium chloride crystals are dissolved in an excess of water, the enthalpy change of solution is found to be +3.9 kJ mol – 1. The change is slightly endothermic, and so the temperature of the solution will be slightly lower than that of the original water.
