simply make the solution of sodium sulfide and sodium hydroxide in water, 105% solution is enough, either deep for few hours or poass electric DC current 1V for instant results.## Alpesh UK

Silver sulphide dissolves in strong acids like sulphuric acid and nitric acid. It however does not dissolve in hydrochloric acid.
Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide.Silver does not react readily with water, acids, or many other compounds. It does not burn except as silver powder.
It is normally called a mirror.
LED or Light emitting diode is based on Electroluminescence.Due to movement of photon in the wire it changes the sides hence during the period it changes it side the light is emitted. This is a rather complex thing.The change in the material of wire leads to different colors :Powdered zinc sulfide doped with copper (producing greenish light) or silver (producing bright blue light)Thin-film zinc sulfide doped with manganese (producing orange-red color)
