There are two possible methods for recovering copper from asolution of copper (II) sulfate, one uses precipitation and theother uses redox.
(a) Copper(II) ions can be precipitated as copper(II)carbonate.
CuSO₄(aq) +Na₂CO₃(aq) â†’CuCO₃(s) +Na₂SO₄(aq)
How many mL of 0.144 M Na₂CO₃would be needed to precipitate all of the copper ions in 25.5 mL of0.165 M CuSO₄? How many grams ofCuCO₃ could be recovered? (Include units in your answer.More information.)
Na₂CO₃Â Â Â Â ___
CuCO₃Â Â Â Â _

(b) Copper(II) ions can be displaced by aluminum metal.
3 CuSO₄(aq) + 2 Al(s) â†’Al₂(SO₄)₃(aq) + 3Cu(s)
How many grams of Al would be needed to displace all of thecopper ions in 25.5 mL of 0.165 M CuSO₄? Howmany grams of Cu could be recovered? (Include units in your answer.More information.)
