Measurement of CO2 solubility in NaCl brine solutions at different temperatures and pressures using the potentiometric titration method

The solubility of CO2 in brine is one of the trapping mechanisms by which the CO2 is sequestrated in aquifers. In this research, an unconventional method, called the potentiometric titration, was used to obtain the solubility of CO2 in distilled water and NaCl brine. The solubility data for the low...
