The salt copper(II) sulfate is soluble in water. When 2.19 g CuSO4 is dissolved in 102.00 g water, the temperature of the solution increases from 25.00 °C to 27.28 °C. Based on this observation, calculate the dissolution enthalpy, ΔdissH, of CuSO4. Assume that the specific heat capacity of the solution is 4.184 J g-1 °C-1 and that the energy transfer to the calorimeter is negligible.

In a dry evaporating dish 7.50 g solid copper (II) sulfate pentahydrate was dissolved in 30.0 ml of deionized water at 60.0 o C. While stirring, slowly 1.23 g of iron powder was added to the solution. The solution was allowed to sit for 10 minutes and then the liquid from the evaporating dish was decanted. The solid was washed with cold deionized water and dried on a hot plate. The weight of the dry solid in the evaporating dish...

12 If white anhydrous copper(II) sulfate powder is left in the atmosphere it slowly absorbs water vapour giving the blue pentahydrated solid. Cuso (s) + SH,O(1) CuSO, SH,O(s) (anhydrous) (pentahydrated) It is difficult to measure the enthalpy change for this reaction directly. However, it is possible to measure the heat changes directly when both anhydrous and pentahydrated copper(II) sulfate are separately dissolved in water, and then use an energy cycle to determine the required enthalpy change value, AH,, indirectly. AH...
