2+ will have a larger Delta(E) than that of [Cu(H2O)6]2+. That is why [Cu(NH3)4(H2O)2]2+ in aqueous solution absorbs yellow-green color and gives out its complementary deep blue color, and [Cu(H2O)6]2+ absorbs orange yellow color and gives out pale blue color.
color of the solution changes from colorless to light blue. The color turns from light blue to light brown solutions upon adding TA solution into the mixture. After 20 min of reaction time, the solution color changed to a dark brown solution. The schematic illustration of the one-pot ...
