Explosionsexperimente mit selbstgemachtem WASSERSTOFF [𝟰𝗞] | JJChemistry

A few days ago, I bought a 10 liter water bottle. Very practical, but buying is boring and too expensive for rare applications. Therefore, I will produce hydrogen on my own today. During the shooting, I drifted off a bit, so that we will see real blasts and colorful fireballs through hydrogen explosions for the first time on YouTube. The list of the necessary chemicals is clear. As a hydrogen carrier, I use salt acid and in addition a reduction agent is used. Typically a ronelis metal. Since I still have kilowatts of iron powder in stock and it is very cheap, I use iron powder. Aluminum foil would also be an option. The glass equipment in which I produce the hydrogen gas consists of a piston, a drip funnel and a lockable access to which a balloon is attached. Since hydrogen is a gas, as I said, the whole equipment must be tight. I fill the drip funnel with 15 milliliters of smoking salt acid. Smoking salt acid bears its name for a reason. The concentration of the acid is so high that chlorine water gases out of the acid and tears water with it. This creates acid vapors that should not be inhaled or should not be inhaled at all. The iron powder comes in the round pistons. I use a lot of 30 grams to carry out several steps in a row. When salt acid hits the iron powder, two H plus ions are reduced to a hydrogen molecule. Iron is oxidized to iron 2 plus ions and together with chlorine ions from the salt acid forms the soluble green iron 2 chloride. The hydrogen rises and goes the only way out of the tight equipment, into the balloon. During the process, the glass equipment is under the pressure of the balloon. A bursting of the glass is unlikely, but not excluded. I remind you again that hydrogen is extremely inflammable. So it is especially advisable to be careful when there is no face protection. After a few minutes, the reaction is over and the balloon is filled with hydrogen. Hydrogen is much lighter than air and gives the balloon an impressive boost. One liter of air weighs about 1.29 grams at a temperature of 0 degrees Celsius. One liter of hydrogen only 0.09 grams. Thus, one liter of hydrogen could pull 1.2 grams. Now the question arises how much hydrogen is needed to lift a human. For an adult human with a weight of 80 kilograms, 66,667 liters of hydrogen would be necessary. If you do not take into account the mass of the balloon needed for this. Hydrogen is a potent reduction agent and forms explosive mixtures with air. The reaction partner from the air is the oxygen. Hydrogen and oxygen react to a known molecule, namely water. To be honest, I found great pleasure in bringing smaller hydrogen balloons to explode. In the presence of suitable protective equipment, of course. In school, such a hydrogen balloon is often referred to as a blast gas balloon. However, this is wrong. Blast gas is a mixture in which hydrogen and oxygen are both in the balloon. Here the hydrogen is alone in the balloon and the air that lies outside contains just 21% oxygen. I will soon fill this purple balloon with hydrogen and oxygen, i.e. real blast gas. However, I have to go outside because an ignition inside my laboratory would probably push out my entire window front. Here is the finished blast gas balloon. But before that, I will ignite a normal hydrogen balloon so that the difference is clear. And now the blast gas balloon. Dude, that's crazy! This is a completely different level. Since both gases are now concentrated very close together, all molecules react with each other in the shortest possible time. The total energy is released in the fraction of a second. Speaking of energy, the standard formation enthalpy of water is at minus 286 kJ per mole. Assuming that there is 4 liters of hydrogen in this balloon, 12.2 kilocalories are released. So this is what it looks like when just 12.2 kilocalories are burned within microseconds. At the same time as the shooting, I visited a fireworks workshop of my friend Nico, who performed it with his company Explosive Arts. Various special effects were shown, including smaller fireballs and a large fire mushroom. The day was crowned by a music-synchronous firework in the night. Long story short, that motivated me to breathe new life into my hydrogen explosion. Anyone can make a normal hydrogen balloon, but colorful fireballs, well, that would be something. In an experiment that I uploaded last year, I dissolved copper sulfate in salt acid and then added aluminum foil. Hydrogen gas is produced, which burns down ice blue when ignited due to the copper ion. Copper is therefore a candidate for ice blue and green fire. That worked perfectly. For red, a whole test series with different substances and concentrations was necessary. Oh, not burned. I will then make a separate video about colorful fireballs and hydrogen gas balloons. But the result of this video is already three balloons in the colors green, light blue and red. After the first tests were successful, I will now fill the first three balloons with the corresponding colors and hydrogen. So red, turquoise and green, or ice blue and green. And I hope that all three will explode at the same time. I will try that right away. I have already covered about half of the rainbow. That looks very nice. While I fill the balloons in the background, I want to say something about the topic of fireballs on the field. I have consciously made sure that the scenes on the field are set before the rain in May and June. After I have ignited the fireball and felt the force that it has in the open, I can not recommend such actions near the forest. The birds were chirping loudly, but such shots should be the absolute exception. Everything on the garbage was cleanly collected. That's probably the least I could do afterwards. Here are the three balloons now, in about the same size. Unfortunately too little filled to float. But that's okay, because I have to be a little careful. I'm not sure how much hydrogen I can ignite here in this room at the same time. That's why I'm touching myself with it now. Now all the balloons are hanging. I have ear protection in it, protective clothing on. I turn off the light now and then we can start. I'm really excited. Since the explosions were overpopulated, I have prepared three new balloons. This time with adjusted video settings. And one more thing before I forget. I will now darken the camera so that the bright explosions do not wash away. So not so white. Otherwise it will be very dark on the camera, so that you can see the colors better. The explosions were not overpopulated this time. The green color, however, was not so optimal. So there is a need for improvement. This really speaks for a separate video about the topic of colorful fireballs from hydrogen balloons. And I'm looking forward to exactly this planned video. I will also try to get more colors out of the hydrogen balloons. Many thanks to my channel members. Without them, such long projects would hardly be possible. The time required for long videos is really immense for me.
