The pot, in addition to being acid-resistant, needs to allow the flow of ions while preventing massive flows of the mixtures.

@@BlueMoonshine I think the pot you used is earthenware, and I can suggest trying either stoneware or porcelain that has only been “bisque-fired”. The earthenware is mainly clay, red iron oxide, and silica, like most clays, but it is not designed to vitrify. Vitrification means that the silica present in the clay has all melted, cooled, and welded together all the other materials in the mix, making it waterproof. Knowing that you need some porosity, but greater integral strength in the pot, you could try using stoneware that has been bisque-fired (this is literally “half-baked”, so the clay is partially vitrified, setting the form, but not yet fully vitrified, and not waterproof, but quite porous instead). Since stoneware is designed to vitrify, and earthenware is not, I suspect that the bisque-fired stoneware would be stronger, and less likely to contaminate your solution. Additionally, stoneware can be bisque-fired within a range of “cones” (which are a measure of heat work, used in all ceramics), and a piece that is bisque-fired to a higher cone will be more durable and less porous, so you might be able to find the sweet spot of balancing the two. Finally, I don’t know the importance of the red iron oxide for the ion flow, but it might help. If so, stoneware clays come in a wide range of iron content, and choosing one that is “buff, red, or black” will increase the iron content, in that order. Happy to clarify if it would be helpful. Thanks for the video!

@@charlieevergreen3514 Thanks for the information, I will have to think about this!

Simply start by making sulfuric acid by using a standard lead electrode. It will work, it will simply decompose a little bit in the solution, adding some pollution, but you can filter it out. Then with the acid you can make a lead dioxide electrode.

So, my estimate was already good.

What does this have to do with the present video?

@@BlueMoonshine The great pyramid was a sulfuric acid reactor according to new evidence.

@@candui7278 OMG, looks like we have another crackpot here!

"Common knowledge when using scales" Thank you, I know this! The reason I did it the way I did is because my scale quickly automatically resets, and doesn't leave me enough time to carefully pour the acid into the cylinder after I press "TARE".

@@BlueMoonshine Then it doesn't work as supposed and should be changed out.

@@dtiydr Yes, but the problem was because of moisture. After I let it dry, it was working properly again. It still works now. That video was made 2 years ago.

@@BlueMoonshine Buy a waterproof one and it will never happen again.

Thanks!

Yeah, I don't think he ever succeeded to fool anyone.

@@BlueMoonshineI highly doubt he even went to college. The paper doesn’t have a proper abstract. No introduction in what he’s trying to prove. No figures, no graphs, no numbers. No citing of sources. The research papers I had to write in college it was important to cite sources. He doesn’t know how to write a science paper. Because he’s not a scientist. He’s nothing.

- To make a battery? - To refine gold? - To make nitric acid in order to make flash cotton? - To synthesize other useful products? Who knows?

1) Make sure that you use cotton, 100% if possible. 2) Make sure your acids have the concentrations that I mentioned, and that you use the same proportions. 3) Make sure that the acid mix is cold. It warms up a lot when you mix the nitric acid with the sulfuric acid, so you need to let it cool off. Make sure the temperature is below 15°C when you dip the paper or cotton balls. 4) I usually let the reaction go for about 15 minutes.

No particular danger that I'm aware of. I know that some companies sell bottles with the mix of gas ready to be used.

Thank you!

Here is how to make a simple rechargeable sulfuric acid battery: ruclips.net/video/0zQYJJz89Wo/видео.html

I will have to think about it.

if you use a high current density, the lead dioxide will not stick to the electrode and fall to the bottom as a powder. you need to increase the voltage till you see little bit of oxygen evolution.

@@janami-dharmam I'll try that!

@@BlueMoonshine also you need to tap the electrode periodically otherwise the PbO2 will hang around the electrode like a slime.

Here is how to make 98% sulfuric acid from Epsom salt. In the tutorial I don't end up with much acid, but everything can be scaled up to get more: ruclips.net/video/l9ifS3ubiBc/видео.html

The crystalization speed will mostly be affected by the surface of the container. The larger the container, the faster the water will evaporate, hence the faster the copper sulfate will have to crystalize in order to prevent an over-saturation of the solution. I really don't know what they use in laboratory. They probably have some specific membranes that select a particular species of ions (charge and size). The clay pot seems to let all ions go through, but it prevents large volumes of fluids from mixing up.

Using a similar setup, you can turn Epsom salt into sulfuric acid if you replace the copper electrode by a lead-dioxide electrode, as I show here: ruclips.net/video/l9ifS3ubiBc/видео.html

The image is reduced, but the aspect ratio is perfectly normal!

Or simply shape the electrode into a flat plate.

Yes, you will make sodium hydroxide in the cathode half-cell, and sodium hypochlorite (bleach) in the anode half-cell.

What for?

Making nitric acid at home is not illegal.

@@BlueMoonshine I know buddy, that's what I'll tell the agents! 🙂

Lead is not poisonous through skin, and requires a much higher temperature (1750°C) to turn into vapor. Don't make an inhalation of the lead dust and you'll be perfectly fine.

Because at the cathode, among the possible reactions, it is the one that has the highest reduction potential that takes place, namely water is reduced into hydrogen gas and OH- ions. The copper doesn't dissolve. At the anode, among the possible reactions, it is the one that has the lowest reduction potential (highest oxidation potential) that takes place, namely the reaction where the oxygen from the SO4-- ion is oxidized, therefore turning the Pb into PbO2.

The points of the tutorial are: - Education in electro-chemistry. - People in many countries don't have access to sulfuric acid in any form (drain opener, acid for battery, ...) because it has been banned, and the method that I propose provide them with an easy alternative. The setup can easily be scaled up to produce more.

That's right!

This is only the 2nd part of the tutorial that gives the general procedure. I will make more parts that will focus onto different components, including on determining the yield of a single computer. I'm traveling abroad right now, but will be back in August.

@@BlueMoonshine I'm looking forward to that! ;)

But also very useful!

Glad you enjoyed it. Please, share the video on your social network.

Thank you! Please, share it on your social networks!

The video is about having sulfuric acid on your HANDS, not on your face or on your scalp. It doesn't call for using it as eye drops or drinking it either.

@@AndreaKarlis thank you for your irrelevant and pointless comment.

@@Muonium1 Well, to be honest, it is your comment that is irrelevant and pointless. The video that you are criticizing discusses about the fact that having sulfuric acid on the hands is not terrible, and you switched the subject to discussing having acid on the face and the skull. This is what is totally irrelevant. The author, to my knowledge, never claimed that it is okay to have this acid on the face or on the skull.

@@AndreaKarlis stay mad.

@@Muonium1 "stay mad" ??? Can you write something that makes sense? At least once?

"Personally, I’d wait and put the 8% acid in a gallon jug until it was full then work with 1 liter at a time and you should get 50 to 100 ml." Sure, I was only showing the concept. "What if you could put acid in very tall narrow vile and allow sediment to settle and maybe cement out a little. You could pipette the cleaner liquid from the top!?" Certainly. Another possibility to get a pure acid is to distill it.

You're welcome. Please, share them on your social networks.

Here is an improved and simpler way of holding the wire around the glass: ruclips.net/video/DBbTJqoNPUo/видео.html

@@BlueMoonshine cheers

And yet it didn't pose any problem in those times, as well as riding a bike without a helmet and without knee protections, or drinking water directly out of the faucet... The human species has become very weak lately.

You use what you have, until you can find better.

@@BlueMoonshine That's objectively misinformation. You can just do a quick google search and find tons of evidence of the long-term neurological effects of consuming lead in almost all forms.

If this is what you think, then you should DEFINITELY watch this 2-minutes video: ruclips.net/video/WzRk6nq9zBc/видео.html

@BlueMoonshine thank you! You definitely made a fair point. However, it is definitely not safe not to point out some sort of disclaimer for the people watching your videos. You might be safe doing your way, but it can be dangerous for others who try to replicate. That being said, I still appreciate your dedication towards science. Big thank you for the great explanation:)

Yes!

You're welcome.
