Iron deposits caused by the corrosion of cast-iron mains are called?

• A. Rust
• B. Blocks
• C. Tubercles
• D. Corroded sections

Answer: (C)

Iron deposits formed as a result of the corrosion of cast-iron mains are referred to as tubercles. These formations occur when iron loses electrons in an electrochemical reaction, leading to the formation of rust and other compounds that accumulate on the inner surface of the pipe. Tubercles are significant because they can restrict water flow and affect the quality of the treated water by harboring bacteria or other contaminants. The other interpretations do not accurately describe these iron deposits. Rust typically refers to the general corrosion product that covers iron and steel and is typically seen as a flaky, reddish substance. While "blocks" could be inferred to suggest built-up material, it lacks the specificity of tubercles. "Corroded sections" refers to areas of compromised integrity in the pipe but does not specifically address the nature or form of the accumulated deposits themselves. Therefore, tubercles encapsulate the specific buildup resulting from the corrosion process in cast-iron mains.
