Production Principle Of Hydrogen Production By Water Electrolysis

When direct current is passed into some electrolyte aqueous solutions, the decomposed substances have nothing to do with the original electrolyte. What is decomposed is water as the solvent, and the original electrolyte still remains in the water. For example, sulfuric acid, sodium hydroxide, potassium hydroxide, etc. all belong to this type of electrolytes. to
When electrolyzing water, since pure water has a very small degree of ionization and low conductivity, it is a typical weak electrolyte. Therefore, the aforementioned electrolyte needs to be added to increase the conductivity of the solution so that water can be electrolyzed into hydrogen and oxygen smoothly.
