Which of the following is NOT a method of corrosion control?

Boiling water treatment is not considered a method of corrosion control. Corrosion control methods primarily focus on altering the conditions in the water system, such as managing the chemical properties of the water, to reduce the rate at which corrosion occurs in pipes and other infrastructure.

pH adjustment can help by altering the acidity or alkalinity of the water, which can influence the corrosive potential of the water. Lowering the pH can increase corrosion rates, while raising it can help protect surfaces.

Using sacrificial anodes is a technique where a more reactive metal is intentionally placed in contact with the water system. This anode corrodes preferentially, thus protecting the underlying metal of pipes or tanks from corrosion.

Inhibitor addition involves introducing chemicals into the water that create a passive film on metal surfaces, which slows down the corrosive process.

Unlike these methods, boiling water does not address the underlying corrosive properties of the water nor does it create any protective barriers. Thus, it is not an effective strategy for corrosion control in water systems.
