Some possibilities have been studied of application of the Crytur 20-15 Ca2+-selective electrode in volumetric analysis especially for determination of the compounds which react with calcium(II) salts to form precipitates or complexes. Titrations with standard calcium(II) nitrate solution have particularly proved useful for determination of aminocarboxylic acids, but sufficiently developed potentiometric titration curves have also been obtained in titrations of fluoride, oxalate and higher carboxylic acid anions (soaps). Also reliable results have been obtained in titrations of Ca2+ besides Mg2+ with standard EGTA solution.

Abstract A method has been developed for the automatic potentiometric titration of sulfate in water-soluble colors, which has the advantage of requiring little sample preparation and attention. A platinum indicating electrode is used with a coated silver reference electrode. The colors are dissolved in 75% alcohol. The sulfate is titrated with lead nitrate solution, using a Hiranuma recording automatic titrator. The method is applicable to the determination of sulfate in all sulfonated certifiable water-soluble colors except External D&C Green No. 1. It is not applicable to the determination of sulfate in the certifiable water-soluble fluorescein colors, namely, FD&C Red No. 3, D&C Orange No. 11, D&C Red No. 22, D&C Red No. 28, and D&C Yellow No. 8. The method is also not applicable to D&C Red No. 19. The
