I had no idea that a flux could be good enough to do that. A big no-no with soldering is to melt the solder onto the iron and then try and paint that onto the workpiece. It never takes properly and the result is a poor joint. Yet here you are just dabbing the solder into the fluxed area and getting an instant joint! amazing! It made me smile that you poured hydrochloric acid into an unstable broken container. Holy cow! I think you need to be a bit more careful than that :-) That's the sort of thing I would do!
Hydrochloric acid is very harsh so the zinc will tame it down a little. This is a very good stuff for soldering but it tends to eat up also the plating on the soldering iron tip. I damaged a lot of tips before I realized what was happening. I myself tried a lot of different stuff and I also found that some rust removers that contain phosphoric acid also work very well even to solder stainless steel.
@@ashchbkv6965 yes they do as the acid in them also attacks the plating. Unfortunately all fluxes tend to. It all depends how harsh the flux is. Knowing that the plating is very thin on the soldering tip we have to take care what to use. It is best to clean the surfaces with some steel wool or fine sandpaper before soldering. The flux also makes some kind of cover not to let the surface oxidize as with heat surfaces although cleaned tend to oxidize faster when heated. I tried soldering on aluminum as well this time I used cooking oil and keeping the solder under the oil not to let oxygen touch the material. I succeeded in this as well.
Thanks for the tips! The most applicable task for this is soldering batteries because its fast reaction which doesn't heating much the batteries and not damaging them. We should just use cheap ass soldering iron 👍
Excellent. Fosforic acid has even a better effect than HCl with dissolved Zinc added to less corrosion in the tip and circuit parts. Dentists use Phosforic acid in their jobs. It is very cheap and small amounts are necessary to aid soldering steel or stainless steel with regular electronic solder
It would be worth annotating that the batteries must be carbon-zinc type, as they are almost unseen in Western countries. Here we use almost solely alkaline and lithium batteries.
Great work,just tell me onething...after the chemical reaction of Zn and HCl is over,then also do we need to wear gloves to touch the material so formed?
The best way is to add more zinc. If there are left over unreacted zinc that means all the acid is used up to dissolve the zinc so the solution should be quite safe. If I still remember my chemistry, the solution is Zinc Chloride.
Hydrocloric acid is highly corrosive. Even when bottled its fumes can destroy nearby metals with corrosion. I know from experience. Would this corrode battery terminals if they were soldered with this?
zinc chloride us almost universally considered unsuitable for electronics soldering. it's a good flux for morons like me who can't solder because it's really effective, but i've always been careful to wash the part clean and also i'm not doing serious work. it's a traditional flux for things like plumbing, but if you're struggling with electronics joints then basically you're supposed to learn how to solder better, because it tends to be corrosive even if you didn't leave excess acid in it. in general, you should be very suspicious of the long term corrosive power of stray chloride ions. fwiw, you can buy ZnCl very cheaply in a nice secure bottle in hardware stores
@@5naxalotl Boa tarde amigo, sou do Brasil, esse fluxo daria certo para soldar latão? mesmo que depois de usar o fluxo eu jogar agua com bicarbonato de sódio para cortar o efeito do ácido, será que ele correi o latão? USANDO O GOOGLE TRADUTOR Good afternoon friend, I'm from Brazil, would this flux work for soldering brass? even if after using the flux I throw water with sodium bicarbonate to cut the effect of the acid, will it run the brass?

I have made this solution many times it becomes transparent after adding zink to hcl but after some days it becomes yellowish again. So will that work? Or have to make new again. Please reply
The concentration ratio does not matter, the more concentrated the acid, the more zinc it needs. The best way is to add more zinc. Until the reaction process is over.
*Very interesting way to make flux. What kind of batteries do you use, saline or alkaline? Do you dissolve the zinc? And I have another recipe for the simplest acid-free liquid flux. Come and visit, you'll be interested;-)*

Hello everyone! I have 2 questions: 1. What is the effect of the chopped zinc in the battery? Is it really important for this? 2. What concentration does the hydrochloric acid have? What percentage is it? There are different percentages in the pharmacies! I would like to thank you very much and hope for an answer. And hopefully “Google” translated everything understandably. Best regards and good luck!!! And. May the force be with you!
Must be used with care excessive quantity promotes corrosion.The fumes are highly corrosive.I have seen that tools near by work area show signs of corrosion.
@@omsingharjit There is no pure Zinc anymore in batteries, especially the chinese ones. There is galvanized steel which has a thin layer of anodized zinc. But you can find PURE ZINC in 1 cent dollar coins after 1983. They are just covered by a thin layer of copper. Thanks and best of luck
@@omsingharjit Zinc is in the form of galvanized steel as I said,, in the external cover no more pure zinc as in the past. Zinc is not magnetc...try a magnet in what you call zinc from a modern battery and you will see
Hi. Attention: Hydrochloric acid (HCl) is a toxic substance besides the convenience it provides. and causes great damage to most surfaces, especially human tissues. For this reason, safety precautions should be kept at the highest level while working with this acid. Hydrochloric Acid, besides being toxic, is irritating to eyes and skin, causing skin burns. and is irritating to the respiratory system. Those who want to do my work in the video should definitely use gloves. And this process should be done in the open air, the gas should not be inhaled...! Thank you
