Seawater at the surface has a pH of about 8.5. (a) Which of the following species has the highest concentration at this pH: H2CO3; HCO3; CO32-? Explain. (b) What are the concentration ratios [CO32-1/IHCO3-] and [HCO3-1/[H2CO3] at this pH? (c) In the deep sea, light levels are low, and the pH is around 7.5. Suggest a reason for the lower pH at the greater ocean depth. (Hint: Consider the presence or absence of plant and animal life, and the effects on carbon dioxide concentrations.)
