Discussion on Electric Charge Number of Complex-ion formed by Fe3+-Sulfosalicylate at Various pH
The distinction of sulfosalicylic acid and salicylic acid was discussed.Because suffosalicylic acid is ternary acid rather than binary acid and dissociates first as a strong acid, then pK2=2.33, and pK2=11.32; the Fe3+ can react with 1 to 3 ligands of sulfosalicylate at variou pH as [Fe(C6Ha.O.COO.SO2)n]3-3n.And some erroneous conclusions involved in the literatures have been corrected.
