Methodology:
Solution was made up by weight. Concentration of solution was verified by measuring the density. (Density was not reported in the paper.) A measured volume of gas was brought into contact with a measured quantity of gas-free solvent. Equilibrium was established by agitation using a magnetic stirrer. The volume of remaining gas was measured. The amount of gas absorbed was estimated from change in volume of gas. Details in original paper.
Sample Information:
- From commercial cylinder. Purity 99.8%.
- Analytical grade.
- Distilled and degassed.
Measurement Errors:
Ambient temperature: δT/K = ±0.2
Mass concentration (m/v) (1): δα = ±2%
System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Nitric acid, $\ce{ HNO3 }$; [7697-37-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
