 Solubility System: Carbon dioxide with Water

---

Components:
   (1) Carbon dioxide; CO2; [124-38-9]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail

Original Measurements:
   Austin, W.H.; Lacombe, E.; Rand, P.W.; Chatterjee, M., J. Appl. Physiol. 1963, 18, 301-4.

Variables:
   Temperature = 293.2 K to 311.2 K

Prepared By:
   C.L. Young

Experimental Data:   (Subscripts 1,2,3, ..., in column headings refer to components 1,2,3, ...)
  

T/K	No.	StandardDeviation	Standard Deviation Note	Bunsen Mean	Bunsen Range
293.2	4	0.0015	a	0.8568	0.0037
297.2	3	0.0003	a	0.7641	0.0005
303.2	3	0.0015	a	0.6503	0.0039
308.2	5	0.0018	a	0.5825	0.0038
311.2	4	0.0014	a	0.5453	0.0021

Notes:
   ^a  σ = Standard deviation.
Unit for α is cm³ (STP) cm^-3 atm^-1

Method/Apparatus/Procedure:
   Humidified gas dissolves in water. After equilibrium established 1 cm³ sample withdrawn and analyzed with manometric Van Slyke apparatus. It was claimed that deionised, distilled water gave the same results as acidified water.

Source and Purity of Materials:
   (1) Commercial sample, no othe details given.
   (2) Distilled acidified with hydrochloric acid (0.01 mol dm^-3).

Estimated Errors:

   Temperature: δT/K = ± 0.1.
