Question

Write the observation and precautions to be taken in the experiment to know favourable conditions of rusting of iron​

Answer 1

Answer:

When a iron is dipped in water it changes to reddish brown after some days

Answer 2

The observation and precautions to be taken in the experiment to know favorable conditions of rusting of iron:

• The divestment of iron to oxygen in the existence of moisture leads to the creation of rust. The atoms of iron and the atoms of oxygen mixed with each other and create iron oxides.
• The process takes place only in the existence of air and moisture. The existence of water vapor in the air and air are two important factors for iron rusting.
• Iron acts as a lacking factor and oxygen act as an oxidizing factor. The atoms of iron give electrons when denuded to oxygen. The chemical reaction of the process is $Fe\rightarrow Fe^{2+} +2e-$.
• Iron gets weak, neglecting its potency, and aspect after rusting. And then, it would not be able to clasp the qualities of iron.
