Silver sulfide is a salt.
but common "salt" or table salt is sodium chloride.
Silver sulfide is composed of silver, a metal, and sulfur, a non-metal; therefore, it is an ionic compound and a salt.
The black tarnish on silver is silver sulfide, Ag2S. Presumably you are boiling silver in a metal pot. The salt water completes an electrochemical cell between the silver sulfide and the aluminum, copper, or iron pot. The oxidized silver in silver sulfide is reduced to silver metal, and part of the metal pot is oxidized; the reaction happens because silver wants to be reduced more than the other metals do. You might imagine that as the metal is oxidized it would become iron, copper, or aluminum sulfide, but the metal sulfides, especially aluminum sulfide, are not so stable. Aluminum sulfide hydrolyzes to aluminum hydroxides and hydrogen sulfide, H2S, the stinky gas, which is probably what you are calling "sulfur".
Ag2S is the chemical formula for silver sulfide, a compound made of silver and sulfur. It is a black solid that is insoluble in water. Silver sulfide is commonly found in nature as a mineral called acanthite.
The word equation for the formation of silver sulfide when silver reacts with sulfur is: Silver + Sulfur -> Silver Sulfide.
Silver sulfide is typically black or gray in color.

Silver sulfide is an ionic compound, and is not a metal.
The formula of silver sulfide is Ag2S.

The reaction between silver sulfide and hydrochloric acid will produce silver chloride and hydrogen sulfide gas. Silver sulfide will react with hydrochloric acid to form silver chloride, which is a white solid precipitate, and hydrogen sulfide gas will be released in the reaction.
No, silver sulfide is not a metal. It is a chemical compound composed of silver and sulfur. Metals are elements that typically have shiny appearances, good conductivity, and malleability. Silver sulfide is a compound formed through the reaction of silver with sulfur.
Yes, salt can be harmful to silver, as it can accelerate tarnishing and corrosion. When silver comes into contact with salt, especially in the presence of moisture, it can lead to the formation of silver sulfide, which darkens the metal. To maintain silver's luster, it's best to keep it dry and avoid exposure to salty environments. Regular cleaning and proper storage can help protect silver from damage.
