Keywords SOLUTION MASTER SPECIES

For all reactions being put in data sets manually, the used master species, if not yet existent, have to be defined using the keyword SOLUTION MASTER SPECIES. 

If elements, species, stability constants, and/or solubility constants that are unavailable in an existing data set, should be used for one task only, it is advisable to define them directly in the input file rather than to change the data set itself. As a declaration in an input file always has a higher rank, it overwrites information of a data set. Like in a data set, the keyword SOLUTION MASTER SPECIES has to be used to define the element (e.g. C), the ionic form (e.g. C03-2), the contribution of the element to alkalinity (e.g. 2.0), the mole mass of the species for... 

Aqueous Species The keyword SOLUTION MASTER SPECIES allows us to define new basis species. To see how this is done, the easiest thing is to look into phreeqc.dat to see how others are defined. Since it has not previously been defined, we have a choice...
