Potassium ferricyanide(III)

Linear Formula: K₃Fe(CN)₆
CAS Number: 13746-66-2
NACRES: NA.21
General Description: Potassium ferricyanide(III) is a potassium salt widely employed as an external indicator in potassium dichromate titrations. A sensor containing a potassium ferricyanide-assisted enzyme electrode for estimating maltose and glucose in samples has been reported. Addition of potassium ferricyanide to the catholyte can improve power generation in microbial fuel cells (MFCs).
