Give one word for the following statement.
The process of coating iron surface with tin.

Open in App

Solution

Iron surface can be protected from rusting by applying a thin coat of tin.
This process is known as tinning.
When iron is exposed to moist air it reacts with the oxygen present in the air to form ferrous oxide.
This is a brown flaky layer coating formed on iron and causes destruction of iron.
This formation is known as rust, and the process is known as rusting.
$\underset{Iron}{4 Fe (s)} + \underset{Oxygen}{2 O_{3} (g)} \to \underset{Ferrous oxide}{2 {Fe}_{2} O_{3} (s)}$
Hence, the answer is tinning.
