Abstract
Kinetics of the formation of monothiocyanato and mononitrilotriacetato complexes of iron(III) in aqueous solution have been studed by using a stopped-flow technique: Fe3++SGN−\oversetk1\undersetk−1\ightleftharpoonsFeNCS2+ FeOH2++SCN−\oversetk2\undersetk−2\ightleftharpoonsFeNCS2++OH− FeOH2++H2nta−\oversetk→Fe(nta)+H+ Rate constants at 25°C and μ=0.5 (NaClO4) are as follows: k=90 M−1 sec−1, k−1=1.6 sec−1, k2=5.1×103M−1sec−1, k−2=10×1013 M−1 sec−1, k=1.0×105 M−1 sec−1. Some discussions are made on the effect of hydroxide ion on the complex formation reactions.Keywords
