Chapter 13.6, Problem 51PP

The ${\text{CO}}_2$ level in the atmosphere has increased over the last few decades due to burning fossil fuels and deforestation. About $35\%$ of the ${\text{CO}}_2$ released into the atmosphere dissolves in the oceans, where it forms ${\text{H}}_2{\text{CO}}_3(\text{aq})$ , which breaks up into ${\text{H}}^{+}(\text{aq})$ and ${\text{HCO}}_3^{-}(aq)$ . The increase in ${\text{H}}^{+}$ makes the ocean water more acidic. One of Peter's research projects is to study the influence of a change in ocean water acidity on coral species, which have calcium carbonate skeletons.

Applications
13.51 a. Write the equation for the dissociation of the slightly soluble ionic compound calcium carbonate, ${\text{CaCO}}_3$ .
b. Write the solubility product expression for ${\text{CaCO}}_3$
