# What would happen if copper (II) chloride was placed into a solution of saturated calcium carbonate???

Precipitation of $\text{copper carbonate}$..........

#### Explanation:

We would LIKELY see the precipitation of $\text{copper carbonate}$, and the fairly insoluble $C a C {O}_{3} \left(s\right)$ would pass into solution to give $C a C {l}_{2} \left(a q\right)$. The colour of the solution would go from dark blue to lighter blue as the $C {u}^{2 +}$ precipitates.

We could represent this process as:

$C u C {l}_{2} \left(a q\right) + C a C {O}_{3} \left(s\right) \rightarrow C u C {l}_{2} \left(a q\right) + C u C {O}_{3} \left(s\right) \downarrow$

The $\text{cupric chloride}$ 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.
