Question

Neena found that Hi anklet turned black after few days. In this process silver is oxidized reduced?

Answer 1

Answer:

Explanation:Here the silver is oxidised........the following reaction takes place:

Silver+Hydrogen sulphide (from air)----->Silver sulphide+Hydrogen

We should always remember that the loss of electron is oxidation and gain of electrons is reduction. Here the initially silver was in its atomic state with no loss of electron but then it loses electrons while combining with sulphur. So loss of electron is oxidation.....
