May 12, 2011· If Silver nitrate is mixed with Sulfur a black, insoluble substance will form. This is the Silver sulfide. Silver forms a complex ion with Ammonia or Cyanide. Potassium cyanide will react with Silver sulfide to produce Sodium sulfide and the Silver cyanide complex. This can then be used to plate Silver by an electrochemical reaction.
