  2. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    That is, energy is added to sodium chloride (table salt) in water, producing sodium hypochlorite and hydrogen gas. Because the reaction takes place in an unpartitioned cell and NaOH is present in the same solution as the Cl 2: 2 NaCl + 2 H 2 O → 2 NaOH + H 2 + Cl 2. any Cl 2 disproportionates to hypochlorite and chloride Cl 2 + 2 NaOH → ...

  3. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl ...

  4. Home canning - Wikipedia

    en.wikipedia.org/wiki/Home_canning

    Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker. A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 °F ...

    View of one slab of hydrohalite, NaCl·2H 2 O. (red = O, white = H, green = Cl, purple = Na). [28] From cold (sub-freezing) solutions, salt crystallises with water of hydration as hydrohalite (the dihydrate NaCl·2 H 2 O). [29] In 2023, it was discovered that under pressure, sodium chloride can form the hydrates NaCl·8.5H 2 O and NaCl·13H 2 O ...

  6. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), [ 1 ] which are commodity chemicals required by industry.

  7. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    For example, hydrochloric acid, HCl, is a strong acid. HCl(aq) → H + (aq) + Cl − (aq) A strong base is one that is fully dissociated in aqueous solution. For example, sodium hydroxide, NaOH, is a strong base. NaOH(aq) → Na + (aq) + OH − (aq) Therefore, when a strong acid reacts with a strong base the neutralization reaction can be ...

  8. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  9. Pascalization - Wikipedia

    en.wikipedia.org/wiki/Pascalization

    Pascalization, bridgmanization, high pressure processing (HPP) [1] or high hydrostatic pressure (HHP) processing [2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.
