Electrolytic waterUsually refers tosalt(e.gsodium sulphate, table salt is not allowed, it will generatechlorine）Of water passing throughelectrolysisThe product generated later.The water after electrolysis is neutral, and other ions can be added, orSemipermeable membraneSeparate to form water of two properties.One of them isAlkaline ionized waterThe other is acidic ionic water.withsodium chlorideElectrolytic water is the electrolyte contained in water, which will containsodium hydroxide, hypochlorite andsodium hypochlorite(If pure water is electrolyzed, onlyHydroxyl ion, hydrogen, oxygen and hydrogen ions).
Chinese name
Electrolytic water
Foreign name
electrolysis of water
Meaning
Water is electrolyzed to generate hydrogen and oxygen
Under certain conditions, the acidic electrolyzed water produced after electrolysis has a bactericidal purpose.According to the electrolysis principle, the oxygen generated at the electrode is lowpHValue (e.g., pH<2.7)chlorineCompound formationHypochloriteorChloriteIonized aqueous solution.
In addition, although some advertisements claim that alkaline electrolyzed water has the purpose of "neutralizing acidic constitution", in fact, when the alkaline water produced by electrolysis reaches the stomach, it will be strongly acidicgastric acidBecome acidic.[1]

The mechanism for preparing electrolytic water is calledElectrolytic cellIts internal main components areElectrode plateAndIonic membraneBoth are technologies applied in many scientific and technological products at present.Common electrolytic water manufacturing equipmentElectrolysis water machineorIonic Water Generator （Ionic Water Generator）。 According to the main components of public water quality, "sulfate", "bicarbonate" or a small amount of "chloride" can be combined with the actual power, flow and other electrolytic conditions to prepare "alkaline ionized water" that is suitable for drinking and has a high concentration of "calcium ion" or "sodium ion" separately, which is the "functional" drinking equipment that demands drinking water.[1]

Before the 1990s, due to problems such as the material of electrolytic plates of electrolytic cells, the operation of electrolytic water machines was still faced with many hardware difficulties in the application of platinum electrode plates. Finally, in the recent 10 years, the development of electrolytic water machines to manufacture drinking electrolytic water was booming.
At the initial stage, use alkaline watercalcium ionandNegative potentialIs the main demand.Since the water quality in Japan is very soft, it is still necessary to add calcium（calcium carbonateComposition) can effectively promote the production of electrolytic water;However, in Taiwan, with the exception of a few areas where the water quality is relatively soft, the water quality in most areas is moderately hard orHard waterOn the contrary, the electrolytic water machine has been operated for only half a year to one year. After all, the electrolytic efficiency drops sharply or becomes invalid because of the serious calcium jam in the electrolytic cell, especially on the surface of the ionic membrane, and the efficacy of electrolytic water becomes impossible to verify.[1]

Use sodium chloride（electrolyte）Aqueous solution, electrolysis can prepare hypochlorite aqueous solution with pH<4.0.During electrolysis, chlorine generated by positive electrode is dissolved in water at a low pH value (<4.0)Hypochloric acid。 According to the theory of "chemistry" and the operation test of actual electrolysis, when the pH of "acidic ionic water" is less than 2.7, "hypochlorite ion" will be oxidized again by "oxygen" separated from "positive electrode", thus generating stronger "chlorine oxyacid", namely "chlorite ion" component.At this time, when the "ORP" of acidic ionic water is measured, its "positive potential" can reach more than (+1100mV). In Japan, this special electrolytic oxidation acidic water is called "electrolytic strong acidic ionic water".[1]

Hydrogen is not only considered as a fuel, but also as a direct substitute for electricity. It cannatural gasThe state of.Unlike electricity, which can be stored (usually in liquid form at low temperatures), gas can be continuously supplied. When the demand for energy is high, it can be stored in advance.Hydrogen will be burned to generate heat energy, or used forfuel cellGenerate electrical energy.[1]
