(17pts) Malachite Synthesis + You will propose a procedure for the malachite synthesis using the materials available and the following chemical reaction 2 CuSO -5 H20 (aq) + 2 Na2CO3(aq) CuCO, Cu(OH)2 (s) + 2 Na2SO (aq) + CO2(g) +9H20 (1) Hint First, you have to prepare solutions of copper(II) sulfate and sodium carbonate. You will need about 5.0 g of CuSO4.5H20 and 3.0 g of Na2CO3. You can dissolve each reagent in 20-25 mL of deionized water. Then you mix two solutions (12pts) 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. 2. Why do you have to be careful while adding the sodium carbonate solution? What is happening? Explain 3. What colour of the precipitate would you expect? 4. How long will you wait after mixing the two solutions? A few seconds or minutes? 5. Do you need to heat or to cool the reaction mixture before isolating the precipitate? 6. How are you going to isolate the precipitate from the liquid? The liquid is called the supernatant 7. Can you weigh out the precipitate immediately after separation? Explain your reasoning
