    The hydroxide ion forms salts, some of which dissociate in aqueous solution, liberating solvated hydroxide ions. Sodium hydroxide is a multi-million-ton per annum commodity chemical. The corresponding electrically neutral compound HO • is the hydroxyl radical. The corresponding covalently bound group –OH of atoms is the hydroxy group.

  2. In this reaction, sodium hydroxide acts as an agent to make the solution alkaline, which aluminium can dissolve in. 2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2. Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications.

  3. Heat required to initiate this reaction is generated by oxidation of a small amount of iron powder mixed with the sodium chlorate, and the reaction consumes less oxygen than is produced. Barium peroxide (Ba O 2) is used to absorb the chlorine that is a minor product in the decomposition. An ignitor charge is activated by pulling on the ...

  5. The relevant reaction is akin to the iodine reaction: thiosulfate reduces the hypochlorite (the active ingredient in bleach) and in so doing becomes oxidized to sulfate. The complete reaction is: 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 ...

  6. Chemical preparations from acetaldehyde and CO /carbon monoxide/ in dilute H2SO4 /sulfuric acid/ at 130-200 °C and 900 atm: Loder, United States of America patent 2265945 (1938 to du Pont); by hydrolysis of hexoses with NaOH /sodium hydroxide/: Lock, United States of America patent 2382889 (1943).

  7. Sodium chloride is the principal extinguishing agent in fire extinguishers (Met-L-X, Super D) used on combustible metal fires such as magnesium, potassium, sodium, and NaK alloys (Class D). Thermoplastic powder is added to the mixture, along with waterproofing (metal stearates) and anti-caking materials (tricalcium phosphate) to form the ...
