The great value of titanous salts in analytical chemistry has become well known through the work of many chemists. Titanous chloride has been used in determining not only inorganic but also many organic substances, which are likely to be colored or to give colored solution on reduction, thus interfering in the accurate determination of end-points in the usual methods of analysis where colored indicators are used. Such difficulties would, of course, be removed by the application of the voltage method. Moreover, so intensely reducing is the titanous ion that an interval of nearly one volt is given between a slight excess of titanous ion and excess of such oxidizing agents as dichromate and permanganate, when the calomel-platinum cell is used, and this wide interval permits the determination with titanium of two oxidizing agents of quite different intensities when present in the same solution.
