Answer 2

"Dissolved oxygen"

Explanation:

Boiler corrosion is the annihilation of heater metal. It happens when the oxygen inside the kettle breaks up into the water. The broke down oxygen then, at that point, causes a response with iron-rich (ferrous) evaporator metal in a cycle known as oxidation. Profound openings and cavities create inside the metal.

Corrosion can harm the inner activities of your kettle in two potential ways - general and pitting. General corrosion makes harm all around the framework, while pitting makes limited disintegration of little pieces of the heater, for example, in tubes.
