Chlorpromazine is oxidized catalytically in the presence of iodide with 1 M hydrogen peroxide in 1 M sulphuric acid medium to form a red radical, which is further oxidized to a colourless sulphoxide. The plot of absorbance at 528 nm vs. reaction time shows an absorbance maximum proportional to the c
