    High spin vs low spin assignment for Vanadyl (acac)2 complex

    I have a question on VO2+ complex. I know that vanadium in VO2+ has +4 oxidation state and it has an unpaired electron in the d-orbital. Based on the notes, they have mentioned that for d4 onwards to d7 has 2 possibilities of arrangement of electrons i.e. high spin and low spin. However, for...

    General Chemistry: Complex Ion Formation Question?

    So the problem states: Treating one mole of Ag2O(s) with 1M (NH4)2SO4 gives as main Ag-containing products: Answer: 1 mole [Ag(NH3)2]+(aq) and 0.5 moles Ag2(SO4)(s) My question is: how do I get to this conclusion? How can a solid precipitate form from sulfate and silver ion in water...
