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

Explanation:

We would LIKELY see the precipitation of $copper carbonate$ $"copper carbonate"$ , and the fairly insoluble $C a C O_{3} (s)$ $CaCO_3(s)$ would pass into solution to give $C a C l_{2} (a q)$ $CaCl_2(aq)$ . The colour of the solution would go from dark blue to lighter blue as the $C u^{2 +}$ $Cu^(2+)$ precipitates.

We could represent this process as:

$C u C l_{2} (a q) + C a C O_{3} (s) \to C u C l_{2} (a q) + C u C O_{3} (s) ⏐ ↓$ $CuCl_2(aq) + CaCO_3(s) rarr CuCl_2(aq) + CuCO_3(s)darr$

The $cupric chloride$ $"cupric chloride"$ 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.
