Which is responsible for the

Question

formation of rust on metals?
oxidation
acid rain
carbonic acid
hydrolysis

Answer 1

The formation of rust on metals, particularly iron, is primarily due to oxidation. Rusting is an electrochemical process where iron reacts with oxygen in the presence of moisture, leading to the formation of iron oxides, commonly known as rust. While factors like acid rain can accelerate the rusting process, the fundamental reaction involves the oxidation of iron.
