The Chemical Engineering Theory section is now launching a \"One Question per Day\" campaign to help everyone reinforce their basic knowledge in chemical engineering. Subsequent campaigns will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" – we hope you will give it your active support! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly; the thread will be closed after 1 day ! To encourage continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: In the production of hydrogen through water electrolysis, what are the effects of too high and too low electrolyte concentrations? Answer: An excessively high concentration of electrolyte increases power consumption and causes corrosion to the asbestos membrane; when it is too concentrated, crystals may precipitate, blocking the liquid and gas channels and preventing the electrolyzer from operating properly. When the concentration of the electrolyte is too low, such as when the KOH concentration is below 20%, it increases power consumption, weakens the passivity of the metal, reduces gas purity, and accelerates equipment corrosion.
Too high levels lead to severe corrosion, while too low levels result in limited electrolysis speed and high energy consumption. Happy Christmas? ? ? Have I traveled through time?
An excessively high concentration of the electrolyte increases power consumption and causes corrosion of the asbestos membrane; when it is too concentrated, crystals may form, blocking the liquid and gas pathways and preventing the electrolyzer from functioning properly. When the concentration of the electrolyte is too low, such as when the KOH concentration is below 20%, it increases power consumption, weakens the passivity of the metal, reduces gas purity, and accelerates equipment corrosion.

Answer: An excessively high concentration of electrolyte increases power consumption and causes corrosion to the asbestos membrane; when it is too concentrated, crystals may precipitate, blocking the liquid and gas channels and preventing the electrolyzer from operating properly. When the concentration of the electrolyte is too low, such as when the KOH concentration is below 20%, it increases power consumption and also affects the metal
The bluntness decreases, gas purity is reduced, and equipment corrosion increases

An excessively high concentration of the electrolyte increases power consumption and causes corrosion of the asbestos membrane; when it is too concentrated, crystals may precipitate, blocking the liquid and gas conduits.
In hydrogen production via water electrolysis, what are the effects of too high and too low electrolyte concentrations respectively? Answer: An excessively high concentration of electrolyte increases power consumption and causes corrosion to the asbestos membrane; when it is too concentrated, crystals may precipitate, blocking the liquid and gas channels and preventing the electrolyzer from operating properly. When the concentration of the electrolyte is too low, such as when the KOH concentration is below 20%, it increases power consumption, weakens the passivity of the metal, reduces gas purity, and accelerates equipment corrosion.
