Distribution of species for H2

(1/1)

Hamed:
Dear all,

I have a basic question. In my model, I am equilibrating a solution with a mineral, and the only gas involved in my model is H2. The distribution of species shows a difference in the amount of H(0) and H2. I wonder what the reason for this difference is and what its physical meaning is. Is it showing the difference between H2(g) and H2(aq)?

Thank you in advance for your contribution.


--- Code: ---H(0)          6.877e-01
H2             3.439e-01   3.439e-01    -0.464    -0.464     0.000     (0) 

--- End code ---

H(0) is giving the number of moles of H in the zero valence state. H2 is giving the moles of the molecule H2(aq). There are two atoms of H(0) for every molecule of H2(aq).
