“…The titration of molybdate with electrogenerated titanium(III) has been compared with other methods (171). Submillimolar amounts of nitroso compounds have been determined by potentiometric coulometric titration with titanium(III) (44,45). An exhaustive study of the electrogeneration of titanium(III) and the effects of ultratrace impurities has appeared (32).…”

The period covered by this survey is from the previous reviews (82, 342,343) through October, 1975. Unless otherwise specified, potentials are with respect to the saturated calomel electrode (SCE). In each area, the intended order of treatment is amperometric, bipotentiometric, and nonamperometric or coulometric. Many coulometric titrations are monitored amperometrically. When thus identified, they have been treated as amperometric titrations.Reviews of amperometric titrimetry include general aspects (326, 335), continuous analysis (185), nonaqueous systems (382), trace determinations (336), inorganic microanalysis (309), determination of antibiotics (364), measurements for industrial uses (253), determination of niobium (234), uses of 8-mercaptoquinoline (28), and of organic reagents in general (265). The value of polarized electrode titrimetry has been discussed (201). In addition to general aspects (31, 67, 142), reviews of coulometric titrimetry concern the electrogeneration of reagents (94), the titration of organic compounds (205), and continuous analysis (186,344,350).

“…This problem was solved by use of CrBr(H20)52+ as reagent, for from this species chromium(II) can be generated rapidly and quantitatively at a mercury cathode in strongly acidic solutions (7). Nitro compounds coulometrically titrated to amperometric end points with about 1% accuracy by this reagent include p-nitrophenol, p-nitroaniline, and o-, m-, and pnitrobenzoic acid (7,8). We became interested in determining whether this method could be extended to the direct determination of other nitro compounds, especially if water insoluble.…”
