Two better titrimetric methods have been developed for determination of carbohydrates such as glucose, fructose, lactose and sucrose, and sugars present in honey and milk. They involve reduction of Cu(II) to Cu(I) by the carbohydrate concerned, and oxidative titration of the Cu(I) with a standard solution of N-bromophthalimide or N-bromosaccharin.
A new redox titrant, Dibromamine-T (N,N'-dibromo-p-toluenesulphonamide) is introduced for use in acetic acid media. Potentiometric titrations of Sb(III), As(III), Tl(I), Fe(II), ferrocyanide, iodide, ascorbic acid, hydroquinone, hydrazine, aniline, phenol and oxine are described. Direct potentiometric titrations of oxinates of Mn, Fe, Co, Ni, Cu and Zn with(More)
A stable new oxidimetric titrant, N-chlorophthalimide in anhydrous acetic acid, is proposed for direct titrations of a variety of simple and complex reductants such as As(III), Sb(III), Fe(II), ferrocyanide, iodide, ascorbic acid, hydroquinone, hydrazine, phenylhydrazine, benzhydrazide, isonicotinic acid hydrazide, semicarbazide, thiourea, aniline, phenol,(More)
Three simple titrimetric methods have been developed to determine iodine-bromine numbers of some edible oils, such as coconut, gingelly, groundnut, mustard, olive, palm olein, and sunflower, using 3 N-chloroimides. The 3 N-chloroimides are N-chlorophthalimide, N-chlorosuccinimide, and N-chlorosaccharin, all of which have recently been developed as potential(More)
Two new oxidimetric titrants, dichlorohydantoin and dibromohydantoin are introduced for use in acetic acid medium, and have been applied to direct potentiometric titration of AS(III), Sb(III), Sn(II), Fe(II), Tl(I), Fe(CN)(6)(4-), I(-), SCN(-), hydrazine, phenylhydrazine, semicarbazide, hydroquinone, oxine and Reinecke's salt, in aqueous acetic acid medium.
