  2. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    For sulfuric acid, computational analysis (with natural bond orbitals) confirms a clear positive charge on sulfur (theoretically +2.45) and a low 3d occupancy. Therefore, the representation with four single bonds is the optimal Lewis structure rather than the one with two double bonds (thus the Lewis model, not the Pauling model). [6]

  3. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [ 4 ] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

  4. Vanadium(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Vanadium(II)_sulfate

    Vanadium(II) sulfate describes a family of inorganic compounds with the formula VSO 4 (H 2 O) x where 0 ≤ x ≤ 7. The hexahydrate is most commonly encountered. It is a violet solid that dissolves in water to give air-sensitive solutions of the aquo complex. The salt is isomorphous with [Mg(H 2 O) 6]SO 4.

  5. SO4 - Wikipedia

    en.wikipedia.org/wiki/SO4

    Sulfate, SO 2− 4, in chemistry, an inorganic ion or a salt of sulfuric acid. SO4 is an acronym for remembering the function of the fourth cranial nerve, the trochlear nerve, which control the superior oblique muscle of the eye. SO(4), the group of rotations in 4-dimensional Euclidean space

  6. Sodium sulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfate

    Hargreaves: 4 NaCl + 2 SO 2 + O 2 + 2 H 2 O → 4 HCl + 2 Na 2 SO 4. The second major production of sodium sulfate are the processes where surplus sodium hydroxide is neutralised by sulfuric acid to obtain sulfate (SO 2− 4) by using copper sulfate (CuSO 4) (as historically applied on a large scale in the production of rayon by using copper(II ...

  7. Ammonium iron(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_iron(II)_sulfate

    Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O.Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate.

  8. Sulfite sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfite_sulfate

    The related ions [O 3 SOSO 2] 2− and [(O 2 SO) 2 SO 2] 2− may be produced in a reaction between sulfur dioxide and sulfate and exist in the solid form as tetramethyl ammonium salts. They have a significant partial pressure of sulfur dioxide. [2] Related compounds are selenate selenites and tellurate tellurites with a varying chalcogen. They ...

  9. Sulfite - Wikipedia

    en.wikipedia.org/wiki/Sulfite

    The structure of the sulfite anion can be described with three equivalent resonance structures. In each resonance structure, the sulfur atom is double-bonded to one oxygen atom with a formal charge of zero (neutral), and sulfur is singly bonded to the other two oxygen atoms, which each carry a formal charge of −1, together accounting for the ...
