Question

The nature of an anti-rust solution is _________.

Answer 1

Hint: Rust is a process in which the metal becomes useless and deteriorates the metal. So, there are many processes that are done to stop the metal from rusting like galvanization, connecting the metal with an electropositive element, anti-rust solution, etc. An example of an anti-rust solution is sodium phosphate solution.

Complete answer:
We know that there are many elements in the universe and these are metals, non-metals, and metalloids. Metals are used for various purposes and are very important. We know that the metals are very reactive and can easily react with air and water.
So, when the metal reacts with air and water, the deterioration of metal starts which makes the metal useless. This is known as corrosion and for iron, we can call it rusting. Therefore, many processes are done on the metals so as to stop the corrosion, like galvanization, connecting the metal with an electropositive element, anti-rust solution, etc.
So, using an anti-rust solution is a process when we dip the iron particles into the boiling anti-rust solution and a protective insoluble sticking film is formed. Generally, alkaline solutions of phosphates and alkaline solutions of chromates are known as anti-rust solutions. An example of an anti-rust solution is sodium phosphates solution. So, we can say that the nature of the anti-rust solution is alkaline. The supply of ${{H}^{+}}$ ions, which aid in the oxidation of iron to $F{{e}^{2+}}$, is reduced by the alkaline nature of solutions.

Note:
Metals are used in making many electrical appliances, buildings, etc., so it is very important that the metal doesn’t get corroded easily as it can cause severe damages. Therefore, proper techniques must be used to prevent rusting.
