1. Determine the enthalpy change when 0.025 mol of anhydrous copper(II) sulfate is dissolved in 50
cm of water using the same method as before.
2. Determine the enthalpy change when 0.025 mol of hydrated copper(II) sulfate is dissolved in 50
cm³ of water. (Note that 50 g water less 5 x 0.025 mole of water which comes from the hydrated salt
should be weighed out).

3. Use the values you obtain from 1, and 2. to calculate the value of AH, for the hydration of CuSO4.
4. Evaluate your experiment fully.
