This problem is providing information about possible causes whereby mussel shells are being eroded due to the acidity in the ocean. In such a way, it claims that more acidic oceans dissolve calcium carbonate in a faster way and produce hydrogen carbonate ions, and thus, a feasible explanation is required as well as a hypothesis according to the following choices:
a. Lower CO₂; this reduces the H₂CO₃ and increases the pH.
b. Add CO₃²⁻: this will add base and increase its concentration.
c. Add Ca²⁺: this will increase the precipitation rate of calcium carbonate (correct choice).
<h3>Equilibrium equations:</h3>At first instance, we should recall the equilibrium equations that take place when acidic oceans dissolve calcium carbonate in a faster way:
Where we can see that the first choice is thoroughly discarded as the addition of CO₂ actually increases the ionizable carbonic acid (acidity). Moreover, the addition of CO₃²⁻ may also lead to the formation of more protons-releasing carbonic acid which also contributes to the acidity of the ocean.
<h3>Hypothesis:</h3>Thereby, the correct condition that, for sure, contributes to the preservation of mussel shells will be the addition of Ca²⁺ and the hypothesis will be that it shifts the equilibrium towards the formation of more CaCO₃, the active compound in these shells.
