But still the question of Anfenglin of what to do with the Silverdithionite is unanswered. He wants to use it.
I have to correct myself. The precipitate in that text is metallic silver for the cyanide system. And there will be a sulfite. For a thiosulfate system the precipitate is stated to be similar.
However another (industrial) source states silversulfide to be the precipitate in a thiosulfate system.
Others describe it as black sludge.
