Which of the following is corrosive water?

• A. Water with a pH of 8
• B. Hard water
• C. Water with high concentration of arsenic
• D. Water with a low pH

Answer: (D)

Corrosive water is defined by its ability to dissolve metals and other materials, leading to potential damage in plumbing and water distribution systems. Water with a low pH is acidic, which means it has a higher concentration of hydrogen ions. This acidity increases its reactivity with metals, making it more likely to corrode pipes, fixtures, and other materials that it comes into contact with. In contrast, water with a pH of 8 is considered slightly alkaline and is generally less corrosive. Hard water, which contains high levels of calcium and magnesium ions, is not typically associated with corrosion, as these minerals can even help to form a protective layer inside pipes. Water with a high concentration of arsenic may pose health risks but does not inherently indicate that the water is corrosive in the same way that low pH does. Therefore, the correct identification of corrosive water is primarily linked to its low pH, making it more aggressive and capable of causing corrosion in water distribution systems.
