title: Spectrophotometric study of the mercury(II)-Xylenol Orange chelate.
abstract: The reaction between mercury(II) and Xylenol Orange has been studied in aqueous hexamine medium. The chelate is 1:1 and has an apparent stability constant of 2.4 (+/-0.6) x 10(6) at pH 7 (2.9 M hexamine). Beer's law is obeyed over the concentration range 0.5-2.0 x 10(-5)M mercury(II) when the hexamine concentration is 2.9 M.
