WebOct 22, 2016 · Hydration is defined as the following process (with any salt but using copper (II) sulphate as an example): (1) C u S O X 4 + 5 H X 2 O C u S O X 4 ⋅ 5 H X 2 O ( s) This reaction will only happen if the associated enthalpy Δ h y d H 0 — or more precisely, the associated Gibbs free energy Δ h y d G 0 is negative. WebEnthalpy change of solution. In thermochemistry, the enthalpy of solution ( heat of solution or enthalpy of solvation) is the enthalpy change associated with the dissolution of a substance in a solvent at constant pressure resulting in infinite dilution. The enthalpy of solution is most often expressed in kJ / mol at constant temperature.
WebStep 3: Calculate mount of energy (heat) released or absorbed per mole of solute (ΔH soln) ΔH soln = q ÷ n ΔH soln = molar enthalpy (heat) of solution q = amount of energy (heat) released or absorbed n = moles of …
