Question

Oceanic uptake of carbon dioxide is thus described:
CO₂ (g) + H₂O ⇔ H₂CO₃, K = [H₂CO₃]/P_CO2 = 3 x 10^-2M atm^-1
H₂CO₃ ⇔ HCO₃^- + H⁺, K = [HCO₃^-][H+]/[H₂CO₃] = 9 x 10^-7 moles/L
HCO₃^- ⇔ CO₃² ^- + H⁺, K = [CO₃² ^-][H+]/[HCO₃^-] = 7 x 10^-10 moles/L
Charge balance equation:
[H+] = [OH-] + [HCO₃^-] + 2[CO₃² ]

If the CO₂ concentration in the atmosphere is 300 ppm, what is the pH of the ocean?
