Pratt III Texas Southern University Houston Texas USA Summary Copper phthalocyanine tetra sulfonate pottasium salt, has been found to be very useful as a screening-dye to improve methyl orange end-points. Mixtures of methyl orange and dye in varying proportions have been prepared and tested for their indicator-action. The transformation interval of the indicator is found to change as the concentration of the dye is varied in the mixture. The optimum concentration of the dye to be used with a certain amount of methyl orange is determined so as to give a mixed-indicator that functions most satisfactorily in all titrations where methyl orange is used.
