Notes:
   a  Data taken from a graph by compiler.
   b  c2 = concentration of NH4Cl
   c  c1 = concentration of CO2

Method/Apparatus/Procedure:
   Attainment of the equilibrium was checked by the constancy of CO2 content in 3-5 subsequent samples of gas after saturation of the solution. The concentration of carbon dioxide was determined by titration.

Source and Purity of Materials:
   (1) Source not given. Before contacting with water solutions CO2 was allowed to pass through the vessels with NaHCO3, glass beads, glass wool, and distilled water.
   (2) Nothing specified.
   (3) Distilled.

Estimated Errors:
   Solubility: δc1/c1 = ± 0.06 - 0.2 %
   Temperature: δT/K = ± 0.05
