Question:

The carbon content in seawater is 30 mmol/L (Table 20.2). This includes both HCO3 and CO32− ions. Knowing the pH of seawater is 8.1, what is the ratio of concentrations of these two ions in seawater? (Figure 20.25.)

Data given in Table 20.2

Concentrations of Some Cations and Anions TABLE 20.2 in Seawater Dissolved Concentrations Species (mmol/L)

Data given in Figure 20.25

At low pH, CO is the dominant species. As the pH increases, the bi- carbonate ion concentration increases to
