Jun 6, 2018 at 14:38 comment added David White probably_someone, in my opinion, the answer is "yes". CO2 dissolves in water to make carbonic acid, and there is an equilibrium between CO2 in the vapor phase and carbonic acid in the liquid phase. An ideal solution would not involve this type of chemical reaction between CO2 and water.
Jun 6, 2018 at 3:19 comment added probably_someone @DavidWhite Is the deviation from ideal behavior large enough that this answer is qualitatively incorrect?
Jun 6, 2018 at 2:45 comment added David White I seriously doubt that CO2 behaves like a non-volatile solute, and the answer above implies an assumption of ideal-solution behavior for every mixture. Most mixtures do not exhibit ideal-solution behavior ... fugacity coefficients need to be used to calculate the system pressure in these cases.
