Photochemical Reactions Involving Nitrosylpentacyanoferrate (II) – Bromide System using Cadmium Sulphide as Semiconductor
Sodium nitroprusside contains cyanide ligands that are not easily replaced chemically. An effort has been made to substitute this ligand by another anionic ligand like bromide. The rate of this photochemical reaction has been observed spectrophotometrically in the presence of cadmium sulphide as a semiconductor. The effect of different parameters like pH, intensity of light, concentration of sodium nitroprusside and bromide ion on the rate of this substitution reaction has been studied. The product was isolated and characterized by different analytical methods. A tentative mechanism for this photochemical substitution has been proposed.
