Question

What is the molar solubility of copper(II) carbonate at 25 oC in a solution that is 0.055 M in copper(II) chloride?

I have done one and I am not sure I am doing it correct. If you can show your work for myself to understand. That would be awesome. Thank You!!

Answer 1

It would have been far easier for you to show your work and let us tell you where your weak/strong points are. As it is I do all the typing and you compare. Henceforth, you type and we will compare.
CuCO3(s)==> Cu^2+ + CO3^-
...x.........x.......x

.........CuCl2(aq) ==> Cu^2+ + 2Cl^-
initial..0.055...........0......0
final soln..0.........0.055..2*0.055

Ksp CuCO3 = (Cu^2+)(CO3^2-)
Ksp = (x+0.055)(x)
Solve for x = solubility CuCO3.

Note: This is a common ion problem with the Cu(II) from CuCl2 being the common ion. Therefore the concn Cu(II) is x from the CuCO3 and 0.055 from the CuCL2.
