| Abstract: | The protonation and disssociation of dibromomethyl carboxyazo were studied by spectrophotometric method. The protonation constant is lgkp = - 2.50 and the dissociation contants are pk, = 0.40,pk2 = 1.61,pk3 = 2.54, pk4 =9.31 and p45 = 11.44. The purification of dibromomethyl carboxyazo was also described. |
