Resumen
Henry's law states that at constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The Bubble Stripping Method involves applying Henry's law to determine the concentration of dissolved hydrogen, H2, in ground water. This paper describes the method’s role in achieving restoration of sites that are polluted with chlorinated solvents. Theory and sample calculations are presented, which may be of use to general chemistry lecturers who want to illustrate how a basic chemical principle can find application in the increasingly important field of environmental science.
