Is a silver ring tarnishing a chemical change?
Yes, the tarnishing of a silver ring is a chemical change. It occurs when silver reacts with sulfur compounds in the air, forming silver sulfide, which appears as a black tarnish. This process alters the chemical composition of the silver, making it a distinct chemical change rather than a physical one. Once tarnished, the original properties of the silver cannot be restored without a chemical reaction to remove the tarnish.
