No, cuso4 isnt white and cu(h2o)6 2+ is blue, not purple. Think more into complex solutions and give me an answer what could it be
Accepted Answer
In chemistry, the color of a substance is determined by the absorption and emission of light by its electrons. In the case of coordination complexes, the color is influenced by the specific metal ion and the ligands coordinated to it. [Cu(H2O)6]2+ is a hexaaquacopper(II) ion, which has a pale blue color. This is due to the absorption of light in the red region of the spectrum, which corresponds to an electronic transition from the t2g to the eg orbitals of the copper(II) ion. The addition of ammonia to this solution will result in the formation of a tetraamminecopper(II) complex, [Cu(NH3)4(H2O)2]2+, which has a deep blue color. This is because the ammonia ligands cause a shift in the energy levels of the copper(II) ion, resulting in a different electronic transition and a change in the color of the solution.
