Answer:

potassium carbonate

Explanation:

Let us consider the equilibrium for the dissociation of copper I carbonate;

Cu2CO3(s)------>2Cu^+(aq) + CO3^2-(aq)

Now we need to add a substance that has a common ion with the solute. The addition of this substance will decrease the solubility of the solute thereby increasing the concentration of the promote the precipitation of copper(I) carbonate precipitate in the system.

Hence, addition of potassium carbonate  promotes the precipitation of copper(I) carbonate.
