Hello Sir. I find your video very interesting. Can you please make us a video on the chemical tests to be done to check the presence of gold in a hydrogen cyanide solution (Extraction of gold using sodium cyanide)?
Not much would change. Gold might dissolve slightly quicker, but still pretty slowly. Then addition of NaOH will precipitate gold (III) hydroxide I think.
Nice video, I love the music
Verry good I want to sée another vidéo like this

Fery good
Насколько я помню, H[AuCl4] более сильный окислитель, чем HNO2, и можно наоборот восстановить растворённое золото до металлического с помощью нитрита
Когда большая часть соляной кислоты израсходуется на образование хлора, золото начнёт восстанавливаться, полагаю
you need heat it
