Postby Melissa Trieu 1K » Thu Oct 30, 2014 1:07 am. The formula of hydrogen sulfate indicates that it contains one atom of hydrogen and sulfur each with four atoms of oxygen. Is Octet Expansion appropriate when regular Octet bonding is possible (such as using dative bonds)? Are the Phosphate and Sulfate ion diagrams with double bonds an invalid picture? Hydrogen sulfide is insoluble in water, but underground, this gas remains trapped within the water. Sulfuric acid is classified as a strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H 3 O +) and hydrogen sulfate (HSO − 4). My main issue is because they are exceptions to the octet rule when drawing Lewis structure, but at this point I don't think there's much I can do besides memorising them. This yields the expected total of 32 electrons. All 6 of sulfur’s valence electrons are being shared in bonds with oxygen giving a total of 12 valence electrons, an expanded octet. February.
