How can I get hydrogen? How do you inflate a hydrogen balloon?

What is "hydrogen gas"? Do you want to fill a balloon with hydrogen? If you have a hydrogen storage cylinder, you can inflate the balloon directly, if the pressure is too high and it is difficult to control, you need to pass through the pressure reducing valve.

After that, you can control it, or charge the basketball liner first, and then squeeze the basketball liner to inflate the balloon, which is easier to control. You can also use a small bottle to fill it with hydrochloric acid, then put a small amount of zinc, react for a while, put the balloon on the mouth of the bottle, or inflate. Hydrogen cannot be inflated with a "pump".

Tell you how I do it: I usually collect aluminum foil, such as the silver paper in the cigarette box, the chewing gum, or something. When a certain amount is collected, you can buy a bottle of sulfuric acid, an industrial one, dilute it appropriately, and then you can produce hydrogen.

Find a plastic bottle with a small mouth and pour sulfuric acid into it. Punch holes in the lid and plug in the waste pen tube. Put the container you want to collect hydrogen from on it.

Shred the tin foil and close the lid immediately when you put it in the sulphuric acid bottle, and the hydrogen will be collected into the container you want. Note: 1. If you want to blow up balloons, it is best not to use rubber balloons, the pressure is not easy to control, and it is better to use that kind of plastic.

2. If you use a fish tank or something, you can use the drainage method to know if it is full or not. 3. Hydrogen is flammable and explosive, be careful!

First, the principle. The caustic soda solution reacts with aluminum to produce metaaluminate and hydrogen. It can also react with lime water (i.e., calcium hydroxide aqueous solution) and soda ash (sodium carbonate), and then use the caustic soda in its product to react with aluminum to produce hydrogen.

2. Raw materials. Caustic soda, chemical name sodium hydroxide, is industrial caustic soda, available in chemical stores; Aluminum, waste aluminum products, cans can be purchased at the scrap collection station; Clear water, drinking well water or tap water.

The gas generator, which is actually a reactor, can be purchased or made by making your own energy: take a discarded liquefied gas tank, make a hole with a radius of 5 cm on it, use it as a feed port, and then make a strong sealing lid with the removed iron block.

Fourth, operation. 1。Caustic soda and water are prepared into a caustic soda solution with a mass ratio of 4 15, injected into the gas generator, and then put in 3 parts of aluminum (calculated as pure aluminum), and cover the lid.

2。Open the valve and you can inflate the balloon. Of course, balloons can also be replaced with more playful air films. Fill it up and tie it tightly.

5. Precautions.

1。One-time caustic soda should not exceed 500 grams.

2。If the caustic soda is accidentally splashed on the body, immediately rinse it with water repeatedly.

The specific steps to inflate a hydrogen balloon are as follows:

1. First of all, prepare the balloon to inflate the local gas, as shown in the figure below.

2. Before inflating, switch the inflatable pump, press and hold the switch, and the power indicator will be on, as shown in the figure below.

3. Then, the inflator of each balloon has an indicator color, as shown in the blue part, as shown in the figure below.

4. Next, remove the blue ** and put it into the inflatable nozzle of the inflatable pump, as shown in the image below.

5. Then, press down on the inflator to inflate the balloon as shown in the figure below.

6. Next, in the process of inflation imitation, the balloon should always pay attention to the state of inflation, as shown in the figure below.

7. Finally, at this time, filling the balloon can be completed, as shown in the figure below.

The method of homemade hydrogen is as follows:

Buy three 9V batteries in series, find a large bowl and pour salt water, connect two pencil leads to the positive and negative electrodes, insert them into the water, fill the test tube or glass bottle with a lid with water cover on the negative carbon rod in the water, and you can collect hydrogen. Find an iron nail and an appropriate amount of white vinegar, or use an aluminum wire core to react with the toilet cleaner to produce gas, and then use a test tube filled with water to collect the gas produced.

At present, hydrogen is generally produced from natural gas or water gas in the industry, instead of using the method of electrolysis of water with high energy consumption, and the hydrogen produced is widely used in the cracking reaction of the petrochemical industry and the production of ammonia, and the hydrogen molecules can enter the crystal lattice of many metals, resulting in hydrogen embrittlement, which makes the design of hydrogen storage tanks and pipelines need to use special materials is also more complicated.

Hydrogen:

Hydrogen is a highly flammable, colorless, transparent, odorless, odorless and insoluble gas with the chemical formula H. Hydrogen is the smallest known gas in the world in terms of density and relative molecular mass, and can be used as a filling gas for airships and hydrogen balloons. In February 2018, China achieved low-temperature preparation and storage of hydrogen, and won the 2017 Top Ten Scientific Progress in China by the Ministry of Science and Technology.

Hydrogen is a colorless gas and less dense than air (among all gases, hydrogen has the least density. Under standard conditions, the mass of 1 liter of hydrogen is grams, which is much lighter than air for the same volume). Because hydrogen is poorly soluble in water, it can be collected using the drain gas collection method.

In addition, at a pressure of 101 kPa, hydrogen can be converted into a light blue liquid at temperature; , it becomes a snow-like solid. At room temperature, hydrogen is very stable and does not easily react with other substances.

The hydrogen balloon inflation method is as follows:

1. First prepare the balloon to be inflated. Sail years.

2. Before inflating the balloon, you should make a switch operation on the inflator pump, as shown in the figure below, press and hold the switch, and the power indicator will be on.

3. The inflator of each balloon has an indicator color, the blue part as shown in the figure below.

4. Peel off the blue skin and insert it into the inflator nozzle of the inflator pump.

5. Press down on the inflator to inflate the balloon.

6. Always pay attention to the inflated state of the balloon during the inflating process.

7. Finally, just fill the balloon with air, and the sedan brother can do it.

Precautions for the use of hydrogen balloons:

Hydrogen friction with other objects produces static electricity, and when it encounters open flames, high temperatures, and electric sparks, it will cause flammable and explosive hydrogen to burn**.

Hydrogen balloons, light bags or sac-shaped objects filled with hydrogen, hydrogen is the lightest, its density is grams per liter, and the objects that can float upwards by the buoyancy of hydrogen are called hydrogen balloons.

Hydrogen balloons generally include rubber hydrogen balloons, plastic film hydrogen balloons and cloth-coated hydrogen balloons.

Larger hydrogen balloons are used to float advertising banners, also called floating hydrogen balloons, meteorologically use hydrogen balloons to detect high altitudes, and militarily use hydrogen balloons to set up communication antennas to attack or distribute leaflets, and the internal frequency of hydrogen balloons is close to 20Hz.
