Model III:  H+ - NH4+ - Na+ - SO42− - NO3 - Cl - H2O, at 298.15 K

Aqueous Solution and Liquid Mixture Calculation

Here, the model determines the equilibrium state of a system containing liquid water, ions, ammonia, and/or organic compounds. Solids, and a second hydrophobic organic phase, can form but no partitioning of water or trace gases into the vapour phase is allowed to occur. Specify the problem in the input fields below.

Solution Temperature

The temperature is fixed at 298.15 K.

Solid Phases

Check the boxes below to prevent the formation of selected solids, as many as desired. This enables the properties of metastable, supersaturated, aqueous aerosols to be investigated. (The default for each calculation is that all solids can form.)

Omit the following solids:

(NH4)2SO4 (NH4)3H(SO4)2 NH4HSO4
NH4NO3 NH4Cl 2NH4NO3 · (NH4)2SO4
3NH4NO3 · (NH4)2SO4 NH4NO3 · NH4HSO4 Na2SO4
Na2SO4 · 10H2O NaNO3 NaNO3 · Na2SO4 · H2O
NaCl Na3H(SO4)2 NaHSO4 · H2O
NaHSO4 NaH3(SO4)2 · H2O Na2SO4 · (NH4)2SO4 · 4H2O
