Method/Apparatus/Procedure:
Attainment of the equilibrium was checked by the constancy of $\ce{CO2}$ 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:
- Source not given. Before contacting with water solutions $\ce{CO2}$ was allowed to pass through the vessels with $\ce{NaHCO3}$, glass beads, glass wool, and distilled water.
- Nothing specified.
- Distilled.
Estimated Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δc1/c1 = ±0.06 - 0.2%
Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Ammonium chloride, $\ce{ NH4Cl }$; [12125-02-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
