Abstract:
Results of a preliminary test for the polarographic reduction of titanium (IV) perchlorate, chloride and sulfo‐salicylate are reported. A single wave with half‐wave potentials ranging from −0.78 to −0.91 volts vs S.C.E. in the pH range 1.2‐2.1, is ascribed to the one‐electron irreversible reduction of titanium (IV) perchlorate and chloride complexes. Two waves have been observed in the c.v. curves of titanium (IV) sulfo‐salicylate in the presence of perchloric acid; the first with half‐wave potentials ranging from −0.37 to −0.41 volts vs S.C.E. is attributable to the one‐electron reversible reduction of titanium (IV) sulfo‐salicylate, and the second at −0.93 volt to the irreversible reduction of titanium (IV) perchlorate. Four waves, denoted by I, II, III and IV, with half‐wave potentials of ca. −0.20, −0.56, −0.80 and −1.0 volts vs . S.C.E. have been observed in the c.v. curves of titanium (IV) subsalicylate in the presence of hydrochloric acid. Wave I is the prewave of sulfo‐salicylic acid, wave II is attributable to the one‐electron reversible reduction of titanium(IV)‐sulfo‐salicylate, wave III to the nearly reversible reduction of titanium (IV) chloride, and wave IV to the reduction of basic or polymerized titanium complexes.
