Abstract

Reduction of [PtCl6]2− by L-ascorbic acid (H2ASc) in 0.1 M aqueous acid medium has been investigated spectrophotometrically under pseudo-first order condition at [PtCl6]2− = 0.005–0.007 mol dm−3, 0.05 ≤ [H2ASc]/mol dm−3 ≤ 0.3, 298 K ≤ ≤ 308 K, [H
Pt(IV)(aq)在盐酸水溶液中氧化l -抗坏血酸的动力学及机理
在准一阶条件下,研究了l -抗坏血酸(H2ASc)在0.1 M酸性水介质中对[PtCl6]2−的还原作用:[PtCl6]2−= 0.005 ~ 0.007 mol dm−3,0.05≤[H2ASc]/mol dm−3≤0.3,298 K≤≤308 K, [H]
