  2. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH.It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −.

  3. Parikh–Doering oxidation - Wikipedia

    en.wikipedia.org/wiki/Parikh–Doering_oxidation

    The Parikh–Doering oxidation is an oxidation reaction that transforms primary and secondary alcohols into aldehydes and ketones, respectively. [1] The procedure uses dimethyl sulfoxide (DMSO) as the oxidant and the solvent, activated by the sulfur trioxide pyridine complex (SO 3 •C 5 H 5 N) in the presence of triethylamine or diisopropylethylamine as base.

  4. Sodium thiosulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_thiosulfate

    4 NaClO + Na 2 S 2 O 3 + 2 NaOH → 4 NaCl + 2 Na 2 SO 4 + H 2 O. Similarly, sodium thiosulfate reacts with bromine, removing the free bromine from the solution. Solutions of sodium thiosulfate are commonly used as a precaution in chemistry laboratories when working with bromine and for the safe disposal of bromine, iodine, or other strong ...

  5. Karl Fischer titration - Wikipedia

    en.wikipedia.org/wiki/Karl_Fischer_titration

    The elementary reaction responsible for water quantification in the Karl Fischer titration is oxidation of sulfur dioxide (SO 2) with iodine: . H 2 O + SO 2 + I 2 → SO 3 + 2 HI. This elementary reaction consumes exactly one molar equivalent of water vs. iodine.

    en.wikipedia.org/wiki/Saponification

    C 3 H 5 (O 2 C(CH 2) 16 CH 3) 3 + 3 NaOH → C 3 H 5 (OH) 3 + 3 NaO 2 C(CH 2) 16 CH 3. This process is the main industrial method for producing glycerol (C 3 H 5 (OH) 3). Some soap-makers leave the glycerol in the soap. Others precipitate the soap by salting it out with sodium chloride.

  7. Sodium sulfite - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfite

    Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3.A white, water-soluble solid, it is used commercially as an antioxidant and preservative.

  8. Sulfur trioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_trioxide

    The molecule SO 3 is trigonal planar.As predicted by VSEPR theory, its structure belongs to the D 3h point group.The sulfur atom has an oxidation state of +6 and may be assigned a formal charge value as low as 0 (if all three sulfur-oxygen bonds are assumed to be double bonds) or as high as +2 (if the Octet Rule is assumed). [7]

  9. Molecular autoionization - Wikipedia

    en.wikipedia.org/wiki/Molecular_autoionization

    In chemistry, molecular autoionization (or self-ionization) is a chemical reaction between molecules of the same substance to produce ions.If a pure liquid partially dissociates into ions, it is said to be self-ionizing.
