Question

Define the following: (i) Rusting (ii) Galvanisation​

Answer 1

Explanation:

Rusting : The process of formation of a reddish-brown substance on the surface of the iron objects in the presence of flaky moisture and air is called rusting.

Galvanisation: Galvanisation is the process of applying a protective zinc coating to iron or steel to prevent rusting.

Answer 2

Answer:

1. Rusting:

testing of iron is a chemical reaction.

Two conditions essential required for the rusting of iron

• presence of oxygen
• presence of water or water vapour

Galvanisation:

the process of depositing a coating of zinc metal on iron objects is known as galvanization.

galvanization prevents iron from rusting. water supply pipes or galvanized with their protective layer of metals such as zinc copper chromium, to protect them from rusting.
