Sodium pyrosulfite (Na2S2O5) stimulates the development of allergic reactions and causes diseases of the gastrointestinal tract. Releases toxic gas on contact with acids. If in contact with eyes, may cause eye damage. But this does not prevent this chemical compound from not only releasing gold from solution, but also being a food additive E223. Пиросульфит натрия (Na2S2O5) стимулирует развитие аллергических реакций, вызывает заболевания желудочно-кишечного тракта. При контакте с кислотами выделяет токсичный газ. При попадании в глаза может вызвать повреждение глаз. Но это не мешает этому химическому соединению не только выделить золото из раствора, но и быть пищевой добавкой Е223.
Podle mne jste nedostal vsechno Stribro hned pri prvnim postupu. Na tech folii nema spravne zustat nic krome nepatrnyho a pruhlednyho stinu tech puvodnich nanosu. Ja jsem videl video kdysi davno kde pouzival varici kyselinu dusicnou aby docilil prave toto. Mimo jiny, KDE jste sehnal dusicnou? Ja mam folie z asi 1000 klavesnic (bedna asi 60 x 40 x 40) a ja asi to cely spalim, pak odstranim ten popel s tetrachlorem, pak to vyredukuju elektrolyticky. Jeste se ale musim poradit s jednim profesorem chemie ohledne nejlepsiho postupu.
And it will go green and you can reuse it time and time again if slowdowns just add some more HC it will go dark green and put all kinds of boards in with gold flashing on it floats of and strain gold off and do it again and again put gold fingers in and over night gold floats of copper chloride two it’s called
Hơn 1 kg các chân mạ vàng này ta thu được 6,5 g vàng , cũng nhiều hơn so với lượng vàng có trong IC thông thường ( không kể những con chip máy tính ) ?
One thing bro you had to denox?? How much nitric did you use?? If you start with few mills at a time on heat and with lid on reaction stops put few more mills in until it’s resolved and the more legs you remove before you start you will use less nitric because copper takes a lot of nitric and the more copper you need more liquid to dissolve the salts in but good job we’re is the water for SMB you drop gold you need double solution water???????
Hi moose coin killer from Australia here what I do with my chips first is I put in AP for few weeks or so and it eats all the magnetics out of the chips all the way up and inside 85% so less to eat away with expensive nitric great video should try it out and make a video on it
sulfic acid should be like 96% atleast 86 will not work actually(only little bit). It's long time taking, dangerous, also usage of acid is high. Only one bonus that gold not lost in the process like you can do when burning.
There is no way he got that much from 1kg. You get more like 1 gram. I'm not sure exactly where but he spiked it somewhere along the line there's no way you can get that much from 1 kg!!!!
Another smart guy without a single experience with these connectors, but who knows exactly what is or is not possible. Get them (the type is there) and then judge. Feel free to make your own video exposing me. In the Eastern Bloc, they used to make gold plated pins like that a lot. There are richer pins.
STO ROKOV KEĎ TO TAKTO BUDETE ZÍSKAVAŤ TAK MÁTE 20g zlata a nič z toho zabitý čas ale Číňania a pakistanci a Indovia majú čas na ťažbu zlata 😂😂😂😂😂😂😂😂😂😂
I thought there was something wrong with my computer. The playback speed needs to be increased by 1.25. Will there be another part of the video about the palladium that was in your beaker? 😎
What is the idea from using the mentioned recipe to get rid off tin rather than using only HCl? I soak pcb in HCl with very good results,but I wonder why you use nitric and citric recipe,is there any advantage?
