Indirect determination of ∆H via Hess’s law Conclusion & Evaluation Research question: What is the ∆H/mol of hydration of CuSO4 (anh)? The ∆H/mol of hydration of CuSO4 (anh) is -70.2‚ according to the experiment done in class. It was determined by applying the Hess’s law‚ using two reactions 1) CuSO4-5H2O ----> CuSO4 (aq) + 5H2O 2) CuSO4 (anh) -----> CuSO4 (aq) According to the Hess’s Law‚ which states that the total enthalpy change for a chemical reaction is the same disregarding

Here are the chemical formulas of the reactants for each reaction: • zinc – Zn copper sulfate – CuSO4 In well 1A there was a chemical reaction which turned the zinc black‚ while the copper sulfate was still blue. AX + B → A + BX Zn + CuSO4 → ZnSO4 +Cu • aluminum – Al copper sulfate – CuSO4 In well 2A there was no reaction between the aluminum and copper sulfate. The aluminum floated and there was no change in color

In solutions that used in the experiment were two species are present reaction between CuSO4 and NaOH. In this method of experiment‚ the total molar concentration of the two solutions are held constant‚ but their mole fractions are varied. In the second experiment‚ it was observed the reaction of acid-base in solution of NaOH with HCl in different
