Figure 1: (a) Ultraviolet spectra of 3% sodium hypochlorite, 4% AHa and the bathochromic shift of sodium hypochlorite/AHa mixture. (b) Ultraviolet spectra of 17% ethylenediaminetetraacetic acid, 2% chlorhexidine, 4% AHa and the bathochromic shift of chlorhexidine/AHa mixture. (c) Test tubes depicting the formation of white precipitate (immediately), and yellow precipitate (after 30 min) followed by sedimentation of the yellow precipitate (after 1 h) on mixing 3% sodium hypochlorite and 4% AHa.
