WebStudents remove the water of crystallisation from hydrated copper(II) sulfate by heating. Condensing the vapour produced in a second test tube collects the water. The white anhydrous copper(II) sulfate is then rehydrated and the blue colour returns. This experiment can be carried out in pairs by students. It should take no more than 30–40 ... WebZinc can be obtained by electrolysis of zinc sulfate or by smelting in a process similar to the production of iron from the blast furnace. First the zinc ore is roasted in air, converting it to zinc oxide: 2ZnS(s) + 3O 2 (g) → 2ZnO(s) + 2SO 2 (g) Coke and the roasted ore are fed into the top of the furnace with air blasted in at the bottom.
