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:
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.
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.
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.

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.
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.
