    d-orbital self split or proton split d-orbitals?

    why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the d-orbitals rather than the lone-pairs cause d-orbital splitting energy?

    What's the correct way to count chelate rings in [Co(EDTA)]-?

    Since I can't find a definition I just drew cycles. When to start and end?

    Chemistry Colour of Fe3+

    I've been tasked with writing an equation to show the reaction of the Fe2+ complex with Cl2. I believe that the oxidation state of the Iron has changed, so I would write 2Fe(H2O)(6)^2+ + Cl2 -> 2Cl- + 2Fe(H20)(6)^3+, but I can't be sure this is correct. Is the 2Fe(H20)(6)^3 ion not yellow in...

    Why does boron banana bond here?

    BH4- + H^+ - > H2 + H2B6 Isn't hydride just a H -, simply putting that with an H+ should give a stable BH3 + H2. Why's the banana bonding happening? Also in NaBH4 + I2 - > B2H6 + 2NaI + H2, can i imagine a oxidation like 2BH4- -> BH3 + H2 + 2e? So I can break I2 as 2I -?

    Why does NO3^(2-) get reduced instead of H+ in Cu+HNO3

    doesn't make sense, h+ just has a really nice positive charge which is begging electrons but electrons go to the NO3(^2-) instead? why?

    What happens when Be(OH)2 reacts with acids and alkalies?

    what just happened? if i did this in water could i do something like Zn + H2O > Zn2+ + 2OH- + H2 so you get ZnOH2 which gets another 2 OH added from NaOH to give Na2Zn(OH)4 nowwww... somehow this is dehydrated twice.. how? why? why is this less stable than the oxide?

    A problem in finding enthelpy of metal oxides

    Arrange the energy released upon hydration of Magnesium Oxide,calcium oxide,barium oxide,strontium oxide. I placed Magnesium oxide at the last,since magnesium hydroxide is a stable so lot of energy must be released in order to achieve that state,but the answer says calcium oxide.

    A question regarding the definition of acids and bases

    Hi! I just read in an inorganic chemistry book (by Whitten, et al.) that acids are defined as substances that produce H+ ions in dilute aqueous solutions, and bases are those that produce OH-. To me, this definition implies that a substance that has yet to produce an H+ or an OH- can already be...

    Basicity of hydrides if group 15 elements

    For group 15 elements the order of basicity given is NH3 > PH3 > AsH3 > SbH3 > BiH3 And order of reducing strength is BiH3 > sbH3 > AsH3 > PH3 > NH3 Why are they in opposite order? Reducing nature means tendency to donate electrons. Basicity means strength of bases and hence as basicity...
