Question

Would copper carbonate precipitate from aqueous solution by treatment of calcium carbonate by copper(II) chloride?

Answer 1

I would think so......

Explanation:

And we would represent the equation by.....

`CaCO_3(s) + CuCl_2(aq) rarr CuCO_3(s)darr+ CaCl_2(aq)`

And how would you know whether the reaction would occur? How else but by experiment?

It is a fact that the `K_"sp"` of `"copper carbonate"` is `1.4xx10^-10`. And the `K_"sp"` of `"calcium carbonate"` is `2.8xx10^-9`. And since copper carbonate is more insoluble than calcium carbonate, metathesis would occur, with the result that blue colour of the solution due to `Cu^(2+)` would slowly(?) dissipate.
