When silver tarnishes when it comes in contact with hydrogen sulfide in the air is that physical or chemical property?
The tarnishing of silver when it comes in contact with hydrogen sulfide in the air is a chemical property. This is because a chemical reaction occurs between the silver and the hydrogen sulfide, leading to the formation of a new compound on the surface of the silver.
What is Ag2S in chemistry?
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.
Word equation for when silver sulfide forms when silver and sulfurS8react?
The word equation for the formation of silver sulfide when silver reacts with sulfur is: Silver + Sulfur -> Silver Sulfide.
If you boil Silver in salt water why does Sulfur form?
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".
What does silver react with?
Silver does not react with oxygen or water, which is why it doesn't tarnish easily. However, it can react with sulfur compounds in the air to form silver sulfide, which appears as a black tarnish on the surface of silver objects.
Is silver tarnishes when it comes in contact with hydro sulfide in the air?
Yes, silver tarnishes when it comes into contact with hydrogen sulfide (H₂S) in the air. This gas reacts with silver to form silver sulfide (Ag₂S), which appears as a dark tarnish on the surface of the metal. The presence of sulfur compounds in the environment, such as those from pollution or certain foods, can accelerate this tarnishing process. Regular cleaning can help maintain silver's shine and reduce tarnishing.

Does the reactants of silver nitrate with potassium sulfide produce a black precipitate?
Yes, when silver nitrate reacts with potassium sulfide, it forms silver sulfide, which appears as a black precipitate. This reaction is often used as a test to detect the presence of sulfide ions.
Is silver tarnishing a physical change?
No, it is a chemical change. The tarnish seen on silver is silver sulfide which formed by the silver reacting from small amounts of hydrogen sulfide in the air. So silver sulfide has been created by a chemical reaction.
What is Ag2S in chemistry?
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.
Word equation for when silver sulfide forms when silver and sulfurS8react?
The word equation for the formation of silver sulfide when silver reacts with sulfur is: Silver + Sulfur -> Silver Sulfide.
Is silver a sulfide?
Silver sulfide is an ionic compound, and is not a metal.
What is the formula for silver (I) sulfide?
The formula of silver sulfide is Ag2S.

What is the color of silver sulfide?
Silver sulfide is typically black or gray in color.
What is the product of silver sulfide plus hydrochloric acid?
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.
