Chapter 17, Problem 136AP

Draw distribution curves for an aqueous carbonic acid solution. Your graph should show fraction of species present as the y axis and $\text{pH}$ as the x axis. Note that at any $\text{pH}$. only two of the three species ${\text{ (H}}_{\text{2}}{\text{CO}}_{\text{3}}{\text{, HCO}}_{\text{3}}{\text{, and CO}}_3^2\text{ )}$ are present in appreciable concentrations. Use the $K_{\text{a}}$, values in Table 16.8.
