To determine whether adding more CaCO₃ (calcium carbonate) to a system will shift the equilibrium to the left or right, we need to consider the context of the chemical reaction and the principle of Le Chatelier.
For the dissociation of calcium carbonate in water, the reaction can be represented as:
\[ \text{CaCO}_3 (s) \rightleftharpoons \text{Ca}^{2+} (aq) + \text{CO}_3^{2-} (aq) \]
When more solid CaCO₃ is added to the system, it does not change the concentration of the reactants or products in the equilibrium expression, because the concentration of a solid does not appear in the equilibrium expression. Therefore, adding more CaCO₃ does not shift the equilibrium position.
In summary, adding more CaCO₃ to the system will not shift the equilibrium left or right; it will remain unchanged.
