How To Make Hydrogen From Water
The method of making hydrogen from water
If you want to make hydrogen from water, there are various methods. First, you can borrow the technique of electrolysis. Prepare a container, fill it with purified water, water or add a little electrolyte, such as sodium sulfate, to increase the conductivity of water. Put two electrodes in it, one is the anode and the other is the cathode, connected to the power supply. After direct current is turned on, the water at the anode loses electrons and oxygen escapes; the water at the cathode gains electrons, and hydrogen is generated. The reaction of the anode is: $2H_ {2} O - 4e ^{-} = O_ {2} ↑ + 4H ^ {+} $; the reaction of the cathode is: $4H_ {2} O + 4e ^{-} = 2H_ {2} ↑ + 4OH ^ {-} $. The total reaction formula is $2H_ {2} O\ stackrel {energized }{=\!=\!=} 2H_ {2} ↑ + O_ {2} ↑ $.
Second, chemical reagents can be used to react with water to produce hydrogen. If metal zinc is co-placed in a container with dilute sulfuric acid, first place zinc in it and slowly inject dilute sulfuric acid. The chemical reaction formula is $Zn + H_ {2} SO_ {4} = ZnSO_ {4} + H_ {2} ↑ $. In this case, sulfuric acid dissociates hydrogen ions, zinc gives electrons to hydrogen ions, and hydrogen ions get electrons into hydrogen atoms, which combine in pairs to form hydrogen molecules.
Or react with active metals such as sodium and water. Take small pieces of sodium and place them lightly in a container of water. Sodium reacts quickly with water, swimming and hissing, with hydrogen escaping. The reaction formula is $2Na + 2H_ {2} O = 2NaOH + H_ {2} ↑ $. Sodium is an active metal with a strong ability to lose electrons. It feeds electrons into hydrogen in water to make it into hydrogen molecules.
When making hydrogen, pay attention to safety. Hydrogen is flammable and explosive, and an open flame should not be used at the operation place. The method of electrolysis requires attention to the choice of electrode materials and the stability of the power supply; the chemical reagent method should properly dispose of reactants and products to prevent pollution and danger. In this way, hydrogen can be obtained and kept safe.
