Henry's Law constant (water solution)
kH(T) = k°H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
k°H = Henry's law constant for solubility in water at 298.15 K (mol/(kg*bar))
d(ln(kH))/d(1/T) = Temperature dependence constant (K)
| k°H (mol/(kg*bar)) | d(ln(kH))/d(1/T) (K) | Method | Reference | Comment |
|---|---|---|---|---|
| 1.×10+11 | M | N/A | Value derived from partial pressure of H2SO4 over a concentrated solution. This can only be considered an order-of-magnitude approximation. The solubility at lower aqueous-phase concentrations should be larger. | |
| 5.×10+14 | M | N/A | Value derived from partial pressure of H2SO4 over a concentrated solution. This can only be considered an order-of-magnitude approximation. The solubility at lower aqueous-phase concentrations should be larger. |
