  2. Sodium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Sodium_hypochlorite

    The density of the solution is 1.093 g/mL at 5% concentration, [22] and 1.21 g/mL at 14%, 20 °C. [23] Stoichiometric solutions are fairly alkaline, with pH 11 or higher [8] since the hypochlorite ion is a weak base: OCl − + H 2 O ⇌ HOCl + OH −. The following species and equilibria are present in NaOCl/NaCl solutions: [24] HOCl(aq) ⇌ H ...

  3. Oxygen reduction reaction - Wikipedia

    en.wikipedia.org/wiki/Oxygen_reduction_reaction

    The oxygen reduction reaction is an essential reaction for aerobic organisms. Such organisms are powered by the heat of combustion of fuel (food) by O 2.Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer.

    Thus, the exchange rates for [Na(H 2 O) 6] + and [Al(H 2 O) 6] 3+ differ by a factor of 10 9. 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 ]

    NaCl + H 2 SO 4 → NaHSO 4 + HCl↑. This reaction occurs at room temperature. Provided there is NaCl remaining in the generator and it is heated above 200 °C, the reaction proceeds further: NaCl + NaHSO 4 → Na 2 SO 4 + HCl↑. For such generators to function, the reagents should be dry.

  6. 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 ...

  7. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
