With HF work I typically have a water bath saturated with CaCl2 nearby. Calcium gluconate gel is essential but having something you can dunk whatever (hand, beaker, tube, etc.) in for immediate fluoride neutralization is always a plus. You can buy CaCl2 by the bucket for cheap since it's used as a drying agent so much. Also, butyl gloves are better than nitrile for HF.
4:51 This mixture does not, but fluorine gas will react with every element in the periodic table except helium and neon, including the other noble gases.
@@wildboy87 No way, the HF is not effective to disolve the gold even when you added with nitric acid. People use HF in gold recovery process because HF could disolve strong metal and leave the gold alone. 1part HF and 3 part nitric acid= pickling solution.
Yeah, from what I read nitric acts as a base in this mixture. HF + HNO3 → F- + H2NO3+ It actually compliments regular AR quite well, because while it doesn't react with any of the noble metals (except maybe Pd), it's great for dissolving all the other stuff that AR can't dissolve.
Persulphuric acid fairly concentrated does work with HCl and it dissolves nearly anything but i don't dissolve hcl acid in it, it might cause chlorine explosion rather I bubble HCl dry while dissolution, But nowadays I use free chlorine has instead;)
No, HSbF6 is when you mix anhydrous HF with SbF5. There were several polyfluorometallic acids made in this video, like H2TiF6, H2ZrF6, H2SiF6, and others, but adding antimony to this mixture does not yield fluoroantimonic acid.
3 pairs of gloves, splash goggles, gas mask, 10ml pipettes for safe transfer of HF, calcium gluconate gel on standby and thank god I didn't need it. I also worked slow and didn't rush.
It would oxidised in such aggressive environment especially osmium has high affinity for oxygen so it will oxide though slowly, Good luck on that osmium electrode because that chlorine smell won't be of chlorine but osmium tetroxide, incredibly toxic
@@createvideo561 From the electrical current?? Because osmium doesn't react with boiling sodium chlorate solutions. Molten NaClO3 is a different story.
@@The_OsmiumChannel as they say-"apply enough volts and it will react", even platinum electrode oxidised though unnoticeably slowly, I guess typical 5v used is enough oxidise fluorine in cases though reacts immediately, Also ameture chlorate cells are not pH controlled so that's a especially aggressive environment cause basic soln tend to retain oxidisers (Spreaded e- density partially stablises the oxidiser species)
