POST-LAB QUESTIONS
1.In step 9, you added water to the dehydrated copper(II) sulfate. Was the rehydration process for the copper(II) sulfate an endothermic process (heat absorbed) or an exothermic process (heat released)? What other observations did you make?
2.A student carried out this experiment with the hydrate of copper(II) sulfate and realized that after the final heating the sample was blue. What effect would this haveon the mass of water calculated and on the formula of the hydrate?
