The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
What else can I help you with?
Is silver tarnishing a chemical or physical change?
no * * * * * A chemical process.
What about tarnishing of silver is chemical or physical change?
It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.
What is Zeisel's method?
Zeisel's method is used to estimate the alkoxy linkages in an organic compound. In this method the organic compound containing alkoxy group is treated with hydrogen iodide and the alkyl halide formed is further treated with silver nitrate to precipitate silver iodide In this reaction only hydrogen iodide can be used because it consists of an ionic bond, while HF, HCl, HBr contain covalent bond where an iodide ion is liberated which forms a precipitate with silver nitrate. The silver iodide can be weighed and from its weight the number or alkoxy group can be estimated.
What did Spencer Silver invent?
Silver invented Post-It Notes. He was trained as a chemist.
Can silver be used to make electrical wires?
Silver is used as a low resistance conductive material. Contactors and relays contact points are made of copper and are silver plated to obtain the lowest resistance between the moving contact faces.
Why is a silver platter tarnishing a physical property?
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
Is tarnish of silver physical or chemical change?
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
Is silver tarnishing a physical or chemical change?
Silver tarnishing is a chemical change. It occurs when silver reacts with sulfur compounds in the air to form a layer of silver sulfide on the surface. This chemical reaction changes the composition of the silver, resulting in the tarnished appearance.
Is silver tarnishing a chemical or physical change?

Is tarnishing silver a chemical change?
Tarnish on silver is Silver Oxide, which is oxidised silver. This is indeed a chemical reaction.
Is silver tarnishing a physical property a physical change a chemical change or a chemical property?

Is silver tarnishing is a chemical change?
Yes, silver tarnishing is a chemical change. It occurs when the silver reacts with sulfur compounds in the air to form silver sulfide, which gives silver a black or brownish tint. This chemical reaction cannot be easily reversed, unlike a physical change.
Is tarnishing a physical change?
chemical, e.g. if you have silver, and it tarnishes, the dark spots (the tarnished areas) are actually silver oxide. If it were a physical change, the silver would need to change states of matter. Into gas, liquid or plasma
