    • Abstract

       

      The decomposition of murexide in acidic solutions was studied spectro-photometrically employing different strong acids like HC1, HBr and HNO3 and mixtures of these acids and neutral salts like KCl, KBr, KI and KNO3. The velocity constant k appeared to be a linear function of the concentration C of the strong acid used, and obeyed a relationship:k/min-1=2.56×10-3C The slope of the line was unaffected by the change in the nature of the acid or added salt indicating that the anions had no effect on the velocity constant.
