Question

3.15 Explain how rusting of iron is envisaged as setting up of an
electrochemical cell.​

Answer 1

Answer:

Also, ferrous ions are further oxidized by atmospheric oxygen to ferric ions. These ferric ions combine with moisture, present in the surroundings, to form hydrated ferric oxide (Fe2O3, x)H2O i.e., rust. Hence, the rusting of iron is envisaged as the setting up of an electrochemical cell.
