Answer to Question #70862 in General Chemistry for John

Question

There are two possible methods for recovering copper from a solution of copper (II) sulfate, one uses precipitation and the other uses redox.

Copper(II) ions can be precipitated as copper(II) carbonate.
CuSO4(aq) + Na2CO3(aq) → CuCO3(s) + Na2SO4(aq)

1.) How many mL of 0.35 M Na2CO3 would be needed to precipitate all of the copper ions in 26 mL of 0.43 M CuSO4?
2.) How many grams of CuCO3(s) would be formed from the copper ions in 55.4 mL of 1.71 M CuSO4?
