I am trying to get react to generate a speciation diagram for Al+++,Al3((OH)4)5+,Al2((OH)2)4+,AlOH2+,Al((OH)2)1+,Al(OH)3,Al(OH)4- .In the command pane I put the following:
0.01 molal Na+
0.01 molal Cl-
10 mmolal Al(OH)4-
...Error Al(OH)4- needs to be swapped in to the basis
when I go to the basis pane to add Al(OH)4- or any other Al species or try to swap it I do not find it in the Aqueous list.So I have only Al+++, H+ ,Cl- and H2O in the basis.
continuing with the commands:
pH = 2
slide pH to 8
precip = off
go
Then I get the following message:N-R did not comverge after 400 its,maximum residual = 4.52 e+120,Xi=0.3400...--Didn't wake up,abandoning path.Please help.
