Copper donates electrons to oxygen, which oxidizes the copper and reduces the oxygen: WebbCorrosion in silver. Silver becomes silver sulfide ( Ag 2 S) when it reacts with sulfur and sulfur compounds in the air. Exposed silver interacts with Hydrogen Sulfide H 2 S in the atmosphere to generate Ag 2 S with the hydrogen gas H 2. The reaction is as follows: 2 Ag s + H 2 S g + 1 2 O 2 g → Ag 2 S s + H 2 g.

The oxidation state of a monatomic ion is the same as its charge—for example, Na + = +1, Cl − = −1. The oxidation state of fluorine in chemical compounds is always −1. remove items from windows explorer sidebar
