"• Second column of table indicates solubility at each given temperature in volume of CO2 as it would be measured at 101.3 kPa and 0 °C per volume of water. • The solubility is given for "pure water", i.e., water which contain only CO2. This water is going to be acidic. For example, at 25 °C the pH of 3.9 is expected (see carbonic acid). At less acidic pH values, the solubility will increase because of the pH-dependent speciation of CO2. " - The solubility of co2 in water
