You will propose a procedure for the malachite synthesis using the materials available and the following chemical reaction:
2CuSO₄⋅5H₂O(aq)+2Na₂CO₃(aq)⟶CuCO₃⋅Cu(OH)₂( s)+2Na₂SO₄(aq)+CO₂( g)+9H₂O
(1 Hint: First, you have to prepare solutions of copper(II) sulfate and sodium carbonate. You will need about 5.0 g of CuSO₄⋅5H₂O and 3.0 g of Na₂CO₃.
You can dissolve each reagent in 20−25 mL of deionized water. Then you mix two solutions.
Below is a list of questions to guide you in the development of your procedure. Answer each of these questions before writing your procedure.
1. Can you make the solutions in a beaker, or should they be prepared in volumetric flasks? Is the amount of water important? Explain your reasoning.
