What are the easy ways to extract hydrogen?

The easiest way to produce hydrogen is:

Water Electrolysis 2(H2O) 2(H2) O2 Hydrogen Production Method:

Method. 1. Reaction of active metals with acids (dilute sulfuric acid or dilute hydrochloric acid).

Method. 2. Electrolysis of water.

Method. 3. Water gas method (using carbon and water vapor to react at high temperature to produce hydrogen and carbon monoxide).

Method. Fourth, the high-efficiency catalyst decomposes water into hydrogen and oxygen at room temperature.

Method. 5. Methane is decomposed into elemental carbon and hydrogen at high temperatures (the elemental carbon produced by decomposition is very useful).

You can find some scraps of aluminum from life. Then find some waste acid, or find sodium hydroxide solids, prepare a concentrated solution, and add crushed aluminum chips to make a large amount of hydrogen.

The equation is: 2Al+3H2SO4=AL2(SO4)3+3H2

2al+2naoh+2h2o=2naalo2+3h2

It can be used to prepare hydrogen in the laboratory, and dilute sulfuric acid with zinc granules in the Qipu generator, which is easy to prepare and use, and can also be stopped and opened at any time.

Electrolysis is also possible.

Eggshells are added with sulfuric acid, and sulfuric acid is used for washing. of the kind, collected by the upward exhaust air method. Hehe, the theory is like this, the actual operation is up to you, hehe.

Place the egg shells in vinegar and collect them with upward exhaust air.

Upstairs said wrong! There will be h?s in the eggshellThat's caco3, right? Or use aluminum, you can put it in a medium or strong acid or alkali! ~

Downstairs is not right, people said that they want to live, where do you go to find zinc grains??

Hydrogen from water can be broadly divided into these types:Electrolysis of water. The most widely used method of obtaining hydrogen is the electrolysis of water, however, in this process, the energy consumption is high.

Electrolysis of saturated saline. This method is also known as the chlor-alkali industry.

In the preparation of sodium hydroxide.

At the same time as chlorine, hydrogen is also obtained.

Water and gas method. Carbon and water are displaced at high temperatures to produce hydrogen and carbon oxide.

This method is mentioned in the second compulsory course of high school chemistry in the Soviet Union.

Crack locust active metal replacement. Metals that are more reactive than hydrogen can be used to replace hydrogen from water, such as sodium, potassium, magnesium, etc.

Optical manuscript with catalytic method. This method is an extension of the first method, which uses water as a raw material, through light and a suitable catalyst, to obtain hydrogen more efficiently, safely, and greenly, according to current scientists.

More rational and effective catalysts are being developed.

Laboratories often use zinc to react with dilute sulfuric acid to produce hydrogen.

1. Reaction principle: the metal element with stronger metal activity than hydrogen is used to react with acid to replace the hydrogen element.

Reaction with zinc with dilute sulfuric acid:

2. Required equipment: rubber stopper, test tube, catheter, beaker, zinc granules, dilute sulfuric acid.

3. Preparation process:

To prepare hydrogen by draining the air exhaust method, it is first necessary to assemble and prepare the equipment by using test tubes, beakers and catheters, as shown in the figure, to check the air tightness of the device; Add zinc particles to the test tube, pour an appropriate amount of dilute sulfuric acid, and quickly install the rubber stopper, which shows that there is gas produced in the right test tube, that is, hydrogen.

Hydrogen can be produced in several ways:

1.Produced by chemical reaction: Hydrogen is often obtained by reacting with other substances, such as electrolysis of water, combustion reaction, etc.

2.Purification preparation: Hydrogen often exists vertically or in other gases, such as natural gas, coal gas, etc., and hydrogen can be separated from other gases by purification.

3.Preparation by absorption method: Absorbents, such as sodium carbonate, calcium carbonate, etc., can be used to absorb hydrogen into the absorbent, and then heat and evaporate to purify the hydrogen from the absorbent.

By the way, I guess there is a way to produce hydrogen through gasoline reforming.

Gasoline reforming is a process in which the alkyl groups in gasoline are subjected to catalytic cracking reactions to generate aromatic spike bends and hydrogen.

The advantages of this method are that the hydrogen produced is of higher quality, higher purity, and faster production speed, but the disadvantage is that gasoline reforming requires the use of special catalysts, which is relatively costly.

The laboratory produces hydrogen per acre of land.

Industrial methods for producing hydrogen:

1. Water gas method (main components CO and H2), carbon and water are reacted to generate carbon monoxide and hydrogen under high temperature conditions, and the reaction equation is as follows

2. The method of electrolysis of water to produce hydrogen, electrolysis of water under the condition of electricity, the generation of oxygen and hydrogen, the reaction equation is as follows:

3. Electrolysis of saturated brine, sodium chloride and water under the condition of electricity to generate sodium hydroxide, hydrogen and oxygen, the reaction equation is as follows:

Electrolyzed water generally refers to the product produced by the electrolysis of water containing salts (such as sodium chloride). The electrolyzed water itself is neutral and can be separated by other ions, or it can be separated by a silent semi-permeable membrane to produce water with two properties.

One of them is alkaline ionized water and the other is acidic ionized water. Electrolyzed water with sodium chloride as the electrolyte contained in water will contain sodium hydroxide, hypochlorous acid and sodium hypochlorite after electrolysis (if pure water is electrolyzed, only hydroxide ions, hydrogen gas, oxygen and hydrogen ions will be produced).

Hydrogen Industrial Production Method:

1. Water gas method (main components CO and H, C + H O = high temperature = Co + H) 2, electrolysis of water method to produce hydrogen (2h o = energized ==O + 2H) 3, electrolysis of saturated brine (2NaCl + 2h o = = electrified lead mold = = 2Naoh + H + Cl).

Zinc and dilute sulfuric acid reaction: Zn + H2SO4 = Zn SO4 + H2 There are a large number of bubbles generated, and the zinc particles are gradually dissolved Hydrogen production in the laboratory.

44. Zinc and dilute hydrochloric acid reaction: Zn + 2HCl = Zn Cl2 + H2 There are a large number of bubbles generated, and zinc particles are gradually dissolved to produce hydrogen in the laboratory.

45. Iron and dilute sulfur are acidically reacted: Fe + H2SO4 = Fe SO4 + H2 bubbles are generated, iron nails are gradually dissolved, and the solution is light green.

46. Reaction between iron empty shed and dilute hydrochloric acid: Fe + 2HCl = Fe Cl2 + H2 bubbles are generated, iron nails are gradually dissolved, and the solution is light green.
