Electrolysis Rate Of Solutes in Common Drinking Water

Jul 15, 2024

Taking sulfate as an example, the activity of elemental calcium and sodium is equivalent, and the electrolysis rate of calcium sulfate is slightly higher than that of sodium chloride. The activity of potassium element is much greater than that of sodium, and the electrolysis rate of potassium chloride is much higher than that of sodium chloride.
According to Faraday's law of electrolysis, with the same DC voltage, the stronger the current consumed in electrolysis, the higher the electrolysis rate. At the same voltage and current, the longer the electrolysis time, the higher the electrolysis rate. Taking alkaline ionized water generated by electrolysis as an example, the higher the pH value of the aqueous solution, the higher the concentration of cation precipitation. However, in reality, there is still an upper limit to the concentration of sodium ion precipitation. The pH value is the result of combining the concentrations of all precipitated cations, including hydrogen ions (which do not exist macroscopically), which will be released in the form of hydrogen gas.
