摘要
Ti(IV, III)偶对的形式氧化还原电位在25°C下,在1 M HCl, 2 M NaCl水溶液中,通过使用玻璃和汞电极的无结电池的电动势测量来确定。控制电解可改变钛(III)和钛(IV)的浓度。在全钛浓度较大范围内,在相同离子介质中,相对于摩尔氢电极,搜索到的形式电位的平均值为9±1 mV。
The Formal Redox Potential of the Ti(IV, III) Couple at 25 °C in 1 M HCl 2 M NaCl Medium
The formal redox potential of the Ti(IV, III) couple has been determined at 25 °C in 1 M HCl, 2 M NaCl aqueous medium, by emf measurements of a junction-free cell with glass and mercury electrodes. Ti(III) and Ti(IV) concentrations were changed by controlled electrolysis. The mean value of the searched formal potential, in a large range of total titanium concentration, is 9 ± 1 mV against the molar hydrogen electrode in the same ionic medium.
