Reaction between silver cyanide complex with sodium sulfide?

01 January 1970 1 3K Report

I look for the equation of chemical reaction between silver cyanide complex with sodium sulfide which leads to silver sulfide precipitation. I appreciate sharing your information.

Lukáš Richtera

I suggest simply: 2 AgCN + Na2S ---> Ag2S + 2 NaCN

what can happen is formation of Na[Ag(CN)2]

this can be done by another reactions with NaCN excess e.g.:

AgNO3 + NaCN ---> AgCN + NaNO3

AgCN + NaCN ---> Na[Ag(CN)2]
