Abstract

The second-order rate constants (k) of substitution of water
in pentacyanoaquo:iron(II) ion by nitrite, thiocyanate, sulphite or
nitrobenzene were determined at various ionic strengths {I) in
aqueous solution at 25 oc. The following slopes of the plot of log
k versus J'h were obtained : 2.9 (No2-·), 2.5 (SCN-), 4.4 (S0a2-), and
zero (nitrosobenzene).
