Thank you for fast answer!

Sorry, I didn't asked for charge balance with sulfate but

if I input sulfat with or without  charge, that is

(measurement gave 400 mg/L)

 

S(6) 400.0 as SO4 charge

or

S(6) 400.0 as SO4

 

have I in every case to multiply the phreeq-output

with 96000 to get the resulting SO4 in mg/L

so TOT("S(6)")*96000=SO4 in mg/L ?
