Question

what is the chemical formula of rust

Answer 1

Hey Friend,

___________________

RUST : Its a Type Of Corrosion.

Let's Try to understand now, What Corrosion exactly is..?

Well, Corrosion is eating up of the top layer of any metal due to I
The Presence of Moisture and Oxygen, Hence, Metals Gets Oxidised and Corrosion occurs..

Now, By Rust, We particular mean Corrosion of Iron...

So, The Formula of Rust is : Fe2O3.xH2O

We write `x` because, We don't know the fixed amount of Moisture...

Rusting can be Prevented by,

Galvanisation... It's A Process of coating Iron With Zinc Layer to prevent Rusting...
