A groundwater sample obtained near a septic tank has a pH of 6.90 and HCO3- concentration of 8.25 mmol L-1. The source of bicarbonate is from the carbon dioxide produced from microbes and the process can be presented as the following chemical equation. CO2 (g) + 2H2O (l) ⇌ HCO3- (aq) + H3O+ (aq) Ka = 4.5x10-7 Provided with a Henry’s constant of CO2 as 0.034 M/atm, answer the following questions. Use an ICE table and work backward to determine...

7. (10) The total CO2 (TCO,) concentration of seawater is roughly 2,300 umoles/L; you will recall that TCO2 includes the sum of carbonate (CO3), bicarbonate (HC03) and carbon dioxide (CO2). At normal ocean pH (roughly pH 8) bicarbonate is the most abundant inorganic carbon species and carbon dioxide (CO2 per se) is present at a concentration of roughly 15 umoles/L Typical deep water nitrate and phosphate concentrations are 40 and 3 umoles/L, respectively. Is dissolved inorganic carbon a limiting resource...
