Boiling water can temporarily prevent rusting, but the effect is not permanent.
Here's why:
-
Oxygen Removal: Boiling water removes dissolved gases, including oxygen. Rust (iron oxide) requires oxygen and water to form. Without oxygen, the rusting process slows down significantly or stops altogether.
-
Limited Protection: The protective effect of boiled water is temporary. Once the water cools and is exposed to the air, it will reabsorb oxygen from the atmosphere.
-
Rust Formation Resumes: As oxygen dissolves back into the water, the rusting process will resume, especially if the metal surface is already exposed to water or moisture.
In summary:
Boiling water can temporarily reduce the rate of rust formation by removing dissolved oxygen. However, it does not provide a permanent solution to prevent rusting as the water will eventually reabsorb oxygen and rusting will continue.
