摘要
本文利用Ｈ２Ｏ２＋２Ｉ－＋２Ｈ＋＝Ｉ２＋２Ｈ２Ｏ的氧化还原反应为指示反应，用化学动力学法〔１〕研究Ｔｉ３＋离子与Ｈ２Ｃ２Ｏ４的配位反应，在所研究的浓度范围内，表明了Ｔｉ３＋与Ｃ２Ｏ２－４作用生成１∶１的配合物，其配离子式为〔Ｔｉ（Ｃ２Ｏ４）〕＋，Ｋ稳，〔Ｔｉ（Ｃ２Ｏ４）〕＋＝（７１２±００１）×１０７。
This article studies the coordination reaction between Ti3+ and H2C2O4 by using chemical dynamics with the oxdoreduction reaction of H2O2+2I-+2H+=I2+2H2O as a tracing approach.It works out within the range of the studied concen-tration a coordination compound produced by Ti3+ and C2O2-4 in 1∶1 proportion,with〔Ti(C2O4)〕+ as its coordination formula and its stability constant=(712±001)×107
