Enthalpy change of hydration copper sulfate
WebOct 7, 2024 · To calculate Δ H, we need to divide the enthalpy change by the amount of product, in moles. Since 250 mL of 1 M solutions of each reactant are mixed and they are in a 1:1 stoichiometric ratio, we will produce 0.250 mol (n = C × V mol = 0.250 L x 1.00 mol/L) of product, so: (15.7.7) Δ H m = − 16 .2 kJ 0 .250 mol = 64 .7 kJ mol − 1. WebFeb 22, 2024 · why it is not possible to measure the enthalpy change of hydration of the anhydrous copper sulphate directly? Sounds like you are doing AQA required practical 2. The equation is CuSO4(s) + 5H2O(l) --> CuSO4.5H2O(s) You would have to add exactly 5 moles of H2O to every one mole of CuSO4.

WebConclusion. The enthalpy of solution of CuSO4 is 16 kcal. Electrolysis is an electrochemical process in which current flows from one electrode to the next in an ionised electrolyte solution. Positive ions, or cations, are drawn to the negative electrode, or cathode, while negative ions, or anions, are drawn to the positive electrode, or anode.
