What is the standard enthalpy change of Hydrated Copper ... Dec 07, 2008 · What is the standard enthalpy change of Hydrated Copper (II) Sulphate? The reaction is anhydrous copper (II) sulphate to hydrated copper (II) sulphate 771 kJ/mol. The enthalpy of formation of CuSO4.5H2O is - 2280 kJ/mol. The Enthalpy of formation of water is - 286 kJ /mol. so enthalpy change required is -2280 - (-770 + 5x-286) = - 80kJ/mol Enthalpy Of Formation Of Cuso4 - Prijom Now, this enthalpy change was for the reaction of 50 mL of a 1M CuSO4 solution with 50 mL of 2M KOH solution. 50 mL of 1M CuSO4 solution only contains 0.05 liters * 1 mole/liter = 0.05 moles of CuSO4. If we want the enthalpy change PER MOLE of CuSO4 reacted, … What is the chemical reaction of zinc and copper (II ... Mar 13, 2016 · Explanation - Zinc is more reactive than copper. So, here , on adding zinc to CuSO4 solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution. This is indicated by colour change from blue to colourless. CuSO4 solution ha Chemistry enthalpy help - The Student Room
