  2. Sulfite - Wikipedia

    en.wikipedia.org/wiki/Sulfite

    The structure of the sulfite anion Sulfite is a ligand in coordination chemistry.The structure of Co(ethylenediamine) 2 (SO 3)N 3.[4]The structure of the sulfite anion can be described with three equivalent resonance structures.

  3. Transition metal sulfito complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_sulfito...

    The structure of [Co(ethylenediamine) 2 (SO 3)N 3]. Color code: blue = N, red = O, yellow = S. [1] Transition metal sulfito complexes are coordination compounds containing sulfite (SO 3 2-) as a ligand. The inventory is large. Few sulfito complexes have commercial applications, but sulfite is a substrate for the molybdoenzyme sulfite oxidase. [2]

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  5. Sodium sulfite - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfite

    Structure of anhydrous sodium sulfite. Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na 2 SO 3 initially precipitates as a white solid. With more SO 2, the solid dissolves to give the disulfite, which crystallizes upon cooling. [2] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O

  6. Bisulfite - Wikipedia

    en.wikipedia.org/wiki/Bisulfite

    Solutions of bisulfite are typically prepared by treatment of sulfur dioxide with aqueous base: [3]. SO 2 + OH − → HSO − 3. HSO − 3 is the conjugate base of sulfurous acid, (H 2 SO 3).

  7. Calcium sulfite - Wikipedia

    en.wikipedia.org/wiki/Calcium_sulfite

    X-ray crystallography shows that anhydrous calcium sulfite has a complicated polymeric structure. [9] The tetrahydrate crystallizes as a solid solution of Ca 3 (SO 3)2(SO 4). 12H 2 O and Ca 3 (SO 3)2(SO 3). 12H 2 O. The mixed sulfite-sulfate represents an intermediate in the oxidation of the sulfite to the sulfate, as is practiced in the ...

    en.wikipedia.org/wiki/Sulfate

    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] In this model, the structure obeys the octet rule and the charge distribution is in agreement with the electronegativity of the atoms. The discrepancy between the S−O ...

  9. Sulfurous acid - Wikipedia

    en.wikipedia.org/wiki/Sulfurous_acid

    Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]
