  2. Sulfur oxoacid - Wikipedia

    en.wikipedia.org/wiki/Sulfur_oxoacid

    H 2 S 2 O 5 +5 (of the sulfur atom bonded to 3 oxygen atoms), +3 (of other sulfur atom) Disulfite commonly known as metabisulfite, S 2 O 2− 5: Not known. Sulfurous acid: H 2 SO 3 +4 Bisulfite, HSO − 3 and sulfite, SO 23: Not known. Dithionous acid: H 2 S 2 O 4 +3 Dithionite, O 2 SSO 22: Not known. Sulfoxylic acid: H 2 SO 2 +2 ...

    Electron configuration is also a major factor, illustrated by the fact that the rates of water exchange for [Al(H 2 O) 6] 3+ and [Ir(H 2 O) 6] 3+ differ by a factor of 10 9 also. [4] Water exchange usually follows a dissociative substitution pathway, so the rate constants indicate first order reactions.

  4. Vanadium(III) sulfate - Wikipedia

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

    The compound is prepared by treating V 2 O 5 in sulfuric acid with elemental sulfur: [2] V 2 O 5 + S + 3 H 2 SO 4 → V 2 (SO 4) 3 + SO 2 + 3 H 2 O. This transformation is a rare example of a reduction by elemental sulfur. When heated in vacuum at or slightly below 410 °C, it decomposes into vanadyl sulfate (VOSO 4) and SO 2. Vanadium(III ...

  5. 3D rotation group - Wikipedia

    en.wikipedia.org/wiki/3D_rotation_group

    The group SO(3) can therefore be identified with the group of these matrices under matrix multiplication. These matrices are known as "special orthogonal matrices", explaining the notation SO(3). The group SO(3) is used to describe the possible rotational symmetries of an object, as well as the possible orientations of an object in space.

  6. Sulfurous acid - Wikipedia

    en.wikipedia.org/wiki/Sulfurous_acid

    Sulfuric(IV) acid (United Kingdom spelling: sulphuric(IV) acid), also known as sulfurous (UK: sulphurous) acid and thionic acid, [citation needed] is the chemical compound with the formula H 2 SO 3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO 2 molecule and the bisulfite ion, HSO − 3. [2]

  7. Oxyacid - Wikipedia

    There are several general reasons for this: (1) they may condense to form oligomers (e.g., H 2 CrO 4 to H 2 Cr 2 O 7), or dehydrate all the way to form the anhydride (e.g., H 2 CO 3 to CO 2), (2) they may disproportionate to one compound of higher and another of lower oxidation state (e.g., HClO 2 to HClO and HClO 3), or (3) they might exist ...

    en.wikipedia.org/wiki/Charts_on_SO(3)

    The universal cover of SO(3) is a Lie group called Spin(3). The group Spin(3) is isomorphic to the special unitary group SU(2); it is also diffeomorphic to the unit 3-sphere S 3 and can be understood as the group of unit quaternions (i.e. those with absolute value 1).

  9. Transition metal oxalate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_oxalate...

    The iron centre is reduced (gains an electron) from the +3 to the +2 oxidation state, while an oxalate ion is oxidised to carbon dioxide: 2 [Fe(C 2 O 4) 3] 3− + hν → 2 [Fe(C 2 O 4) 2] 2− + 2 CO 2 + C 2 O 2− 4. The redox reaction has been used to access unusual complexes. UV-irradiation of Pt(C 2 O 4)(PPh 3) 2 gives derivatives of Pt 0 ...
