A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. This page looks at the relationship between enthalpies of solution, hydration enthalpies and lattice enthalpies note: you really ought to have read the pages about hess's law cycles and lattice enthalpies before you solution is one where there is a sufficiently large excess of water that adding any more doesn't cause any further heat to be.

Free essay: calculations the reaction between magnesium metal and sulfuric acid released heat, which melted some of the ice in the calorimeter because ice. Heat of solution or enthalpy of solution chemistry tutorial key concepts a solute dissolves in excess solvent to form a solution: solute + solvent → solution the following describes the use of a polystyrene foam (styrofoam™) cup as a calorimeter to determine the heat of solution of a salt (solid solute) in water (the solvent) 5.
