Precipitation of "copper carbonate"..........

Explanation:

We would LIKELY see the precipitation of "copper carbonate", and the fairly insoluble CaCO_3(s) would pass into solution to give CaCl_2(aq). The colour of the solution would go from dark blue to lighter blue as the Cu^(2+) precipitates.

We could represent this process as:

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

The "cupric chloride" is likely to be a complex salt, and is a label of convenience.

But chemistry is an experimental science, so you must do the experiment yourself, and try to rationalize whatever you observe.
