70% to passTo minimize metal corrosion, boiler water is best kept _______________.
Afairly acidic
Balkaline
Cslightly acidic
Dneutral
AI Explanation
The correct answer is B) alkaline. Boiler water is best kept alkaline to minimize metal corrosion. Alkaline water, with a pH higher than 7, helps form a protective oxide layer on metal surfaces in the boiler, preventing corrosion. This is the recommended practice according to regulations and industry standards for boiler water treatment. The other options are incorrect because: A) Acidic water would accelerate corrosion of metal boiler components. C) Slightly acidic water still provides insufficient protection against corrosion. D) Neutral water, with a pH of 7, does not offer the same level of protection as alkaline water.
