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
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 ?
