Does copper 2 carbonate dissolve in water? ?

Question

Does copper 2 carbonate dissolve in water? Because I have this question:

Describe how this mixture can be separated:

crystals of copper 2 sulfate.5h20 from a mixture of sand, copper 2 sulfate and copper 2 carbonate.

Answer 1

copper carbonate is a sparingly soluble salt....Ksp 4 X 10^-16. So add water and filter .The sand and majority of the CuCO3 will precipitate and can be filtered out. The filtrate is mostly the Cu(II) SO4 with maybe a trace of the CUCO3. If it is cloudy add drop -wise dilute H2SO4 that will convert the contaminating CuCO3 to CuSO4. Then evaporate the aqueous solution slowly with a small string placed in the water. The CuSO4 will begine to crystallize out as blue bulky crystals on the string. Or you can evaporate the solution till nothing remains but the blue cystalline mass. ( less pure )

Answer 2

Which I don't want to seperate sorry. BUT, carbonates are insoluble in water.

1. Group IA and ammonium compounds are soluble.

2. Acetates and nitrates are soluble.

3. Most chlorides, bromides, and iodides are soluble. Except: AgCl, Hg2Cl2, PbCl2, AgBr, HgBr2, Hg2Br2, PbBr2, AgI, HgI2, Hg2I2, PbI2.

4. Most sulfates are soluble. Except: CaSO4, SrSO4, BaSO4, Ag2SO4, Hg2SO4, PbSO4.

5. Most carbonates are insoluble. Except: Group IA cabonates,

(NH4)2CO3

6. Most phosphates are insoluble. Except: Group IA phosphates, (NH4)3PO4

7. Most sulfides are insoluble. Except: Group IA sulfides, (NH4)2S

8. Most hydroxides are insoluble. Except: Group IA hydroxides,

Ca(OH)2, Sr(OH)2, Ba(OH)2

Answer 3

Add water, shake to dissolve the CuSO4, filter, evaporate the filtrate.
