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) →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.)
| Na2CO3Ă‚Â Ă‚Â Ă‚Â Ă‚Â | _____ |
| CuCO3Ă‚Â Ă‚Â Ă‚Â Ă‚Â | _____ |
(b) Copper(II) ions can be displaced by aluminum metal.
3 CuSO4(aq) + 2 Al(s) →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.)
| Al    | ______ |
| Cu    | ______ |
Please be very specific with the answers!! I only have onesubmission left and im very lost!
