Dissociation constant of ferric salicylate complex
« on: December 26, 2007, 02:42:59 AM »
Hi everyone!

I'm searching dissociation constant of ferric (III) salicylate complex at room temperature. Though I've searched for it on many websites, I haven't found it. If you can access some database, please check it for me. Thanks very much for your hel p!

Best regards,

log β1 = 17.44
log β2 = 27.49
log β3 = 35.31 (ionic strength = 3.0)

βi = [ML]/([M][L]i)

Note: L is dissociated form of H2L, so in fact it should be written as L2-.
