THE REDOX FEATURES OF COMPLEX FORMATION REACTIONS OF Hg(II), Ce(IV), Se(VI), Cr(VI), Mn(VII), V(V) WITH CARMOISINE
The activating effect of Mn(VII) ions on V(V), Se(VI) and Cr(VI) complexing ability with carmoisine was established with pH values that are typical of each ion separately, that allow to determinate them without heating of reaction mixture. It is shown that values of the chemical system redox potenti...

| Summary: | The activating effect of Mn(VII) ions on V(V), Se(VI) and Cr(VI) complexing ability with carmoisine was established with pH values that are typical of each ion separately, that allow to determinate them without heating of reaction mixture. It is shown that values of the chemical system redox potential and the medium acidity, which are optimal for each of the investigated metal ions, are critical and important factors that influence complex formation in the systems "M1-M2-CAN". |
