describe the processes that occur when solid copper (II) sulfate dissolves in water
Homework Answers
A reaction electrolysis occurs:
2 CuSO4 + 2 H2O = 2 Cu + O2 + 2 H2SO4
Where there is an exchange of electrons between the substances participating in the reaction (redox reaction) and the valences of the elements change.
If you liked the answer, please rate it positively, you would help me a lot, thanks.

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...
