![5b. Both [Fe(CN)6]*- and [Fe(CN)6]} are toxic because they dissociate cyanide, CNC. Predict which one will be more poisonous,](http://img.homeworklib.com/questions/cf4654a0-1cc6-11ea-a7f5-c3f5000bb01d.png?x-oss-process=image/resize,w_560)
Homework Answers
lesser stable complex can be dissocated easily and releases CN- very fast.
the general point is central metal ion oxidation state increases stability of complex also increases.
in [Fe(CN)6]4- , oxidation state of Fe = Fe + 6 x -1 = -4
= +2
in [Fe(CN)6]3- , oxidation state of Fe = Fe + 6 x -1 = -3
= +3
first complex Fe oxidation state is +2 and in second complex Fe oxidation state is +3. so second complex is more stable and less probability to dissociate.
so [Fe(CN)6]4- is more poisonous
