The solubility of carbon dioxide, krypton, and xenon has been measured at 1 Atm. total pressure and at temperatures of 25, 30, 37, and 45° in distilled water, 0.9 per cent sodium chloride, and .066 M phosphate buffer solution at pH 7.0. The solubility of the gases studied in aqueous solution decreased as the temperature increased. Heats and entropies of solution have been calculated according to Eley's equation (16). The relation between ΔS° and ΔH° at various temperatures is exactly linear in every case, and the slope is approximately equal to 1/T.
