First, choose the form of output required:
Next, specify the problem in the input fields below.
(1) The temperature is fixed at 298.15 K.
(2) The water content of the system must be specified as either a (fixed) ambient relative humidity, or the number of moles of total or liquid water present per m3 of atmosphere. Select one:
Now enter the relative humidity (range 0.1 - 1.0) or moles of water present:
(1) Enter the initial composition of the system:
(2) Select the ions whose amounts in the mixture are being changed. Note that they must both be either cations or anions. Also, the "initial" ion (which is being substituted for) must be present in a non-zero amount in the mixture above.
Initial ion: H+ NH4+ Na+ SO4-- NO3- Cl- Substituting ion: H+ NH4+ Na+ SO4-- NO3- Cl-
Now enter the range of substitution of the initial ion, in mole percent, followed by the number of points to be calculated:
Check the boxes below to disable the partitioning of selected trace gases into the vapour phase. (The default for each gas is that partitioning is calculated.)
Prevent partitioning of the following gases:
