Procedure
1.<Tab/>Prepare 1 molar NaOH solution for liquid feed. Prepare 2 mol% CO2 gas feed.
2.<Tab/>Record base feed conductivity (time = 0)
3.<Tab/>Start vapor feed up the column.
4.<Tab/>Start liquid feed down the column. (Turn on pump 2 after opening valves 6 and 7.)

The experimentally determined Kga values are on the same order as the literature values, indicating some degree of accuracy. However, the literature values follow different trends than the experimentally observed values. Literature reports that as Gx increases, so does Kga. Figure 3, the experimentally determined values, shows that Kga decreases with increasing Gx. Most likely, experimental error caused inaccuracies in the experimental values.
