Henry's law constant for CO2 at 38oC is 2.28 x 10–3 mol/L\cdot⋅atm. Calculate the pH of a solution of CO2 at 38oC in equilibrium with the gas at a partial pressure of 3.20 atm. Assume that all dissolved CO2 is in the form of carbonic acid (H2CO3). Ka1 = 4.3 x 10–7 and Ka2 = 5.6 x 10–11 for carbonic acid.

Calculate the concentration of Co2 in rainwater at 25C using Henry's law. Assume that the water is saturated with air that contains 350 ppm of CO2. The Henry's law constant for CO2 is KH=3.4X10-2 MOL/L-ATM at 15C . Express the result in molarity and ppm. Calculate the concentration of NO in rainwater at 25 C that is in equlibrium with polluted air where the NO concentration is 10 ppm. The Henry's law constant for No is Kh=2x10-4 mol/l-atm at 25C...
