Understanding

The lack of a protective layer in the pipes can cause a similar oxidation reaction to the one occurring in the lead pipes: Fe (s) ➔ Fe2+ (aq) + 2 e–. What is the main consequence of this reaction?

• Rust-colored water

• Increased water pressure

• Improved water taste

• Decreased water temperature
