17.10 Air contains an average of about 0.032 percent by volume of carbon dioxide, and Henry's law constant K for carbon dioxide in water at 20°C is 26 atm/M. (a)

Using Eq. (2.15), calculate the concentration of carbon dioxide in a water sample when in equilibrium with atmospheric carbon dioxide at sea level. (b) On the basis of the calculation in part (a), what will occur when a sample containing 10 mg/L of carbon dioxide is vigorously exposed to the air prior to titration for carbon dioxide?
