Enthalpy change of hydration copper sulfate

WebNow do the calculation: Hess's Law says that the enthalpy changes on the two routes are the same. That means that: ΔH - 3267 = 6 (-394) + 3 (-286) Rearranging and solving: ΔH = 3267 + 6 (-394) + 3 (-286) ΔH = +45 kJ mol -1. Note: If you have a good memory, you might remember that I gave a figure of +49 kJ mol -1 for the standard enthalpy ... 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.
