  2. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    2 NaCl + 2 H 2 O 2 NaOH + H 2 + Cl 2. Without a membrane, the OH − ions produced at the cathode are free to diffuse throughout the electrolyte. As the electrolyte becomes more basic due to the production of OH −, less Cl 2 emerges from the solution as it begins to disproportionate to form chloride and hypochlorite ions at the anode:

  3. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    In part because of its high polarity, HCl is very soluble in water (and in other polar solvents). Upon contact, H 2 O and HCl combine to form hydronium cations [H 3 O] + and chloride anions Cl − through a reversible chemical reaction: HCl + H 2 O [H 3 O] + + Cl −. The resulting solution is called hydrochloric acid and is a strong acid.

  4. Sodium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Sodium_hypochlorite

    3 ClO − + H + HClO 3 + 2 Cl −. In particular, this reaction occurs in sodium hypochlorite solutions at high temperatures, forming sodium chlorate and sodium chloride: [25] [26] 3 NaOCl(aq) 2 NaCl(aq) + NaClO 3 (aq) This reaction is exploited in the industrial production of sodium chlorate.

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

  6. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    2 HCl + Na 2 Fe(CO) 4 2 NaCl + H 2 Fe(CO) 4. Reaction between an acid and a carbonate or bicarbonate salt yields carbonic acid, which spontaneously decomposes into carbon dioxide and water. The release of carbon dioxide gas from the reaction mixture drives the reaction to completion.

    2 h 2 o 2 h 2 + o 2 Efficient and economical water splitting would be a technological breakthrough that could underpin a hydrogen economy . A version of water splitting occurs in photosynthesis , but hydrogen is not produced.

  9. Metal peroxide - Wikipedia

    en.wikipedia.org/wiki/Metal_peroxide

    Na 2 O 2 + 2 HCl 2 NaCl + H 2 O 2 Upon heating, the reaction with water leads to the release of oxygen. [ 1 ] Upon exposure to air, alkali metal peroxides absorb CO 2 to give peroxycarbonates.
