WebAim To determine the enthalpy change for the reaction between zinc and copper sulphate. Zn (s) + CuSO4 (aq) ZnSO4 (aq) + Cu (s) Introduction In the study of energy (thermodynamics) the system refers to the reacting chemicals (zinc and copper sulphate solution) and the surroundings is everything else (atmosphere. WebAnswer (1 of 2): That’s an interesting observation. Apparently, the enthalpy of solvation of hydrated CuSO4 is negative while the binding of waters to the Cu(II) cation and SO4(^-2) anion when they are dissolved is characterized by a positive delta-H of solution. The sulphate anion is also hydrat... raj pre papagaje
