A chemical explanation for using copper pipes in plumbling rather than iron is that

copper is more resistant to corrosion than iron. Iron pipes can rust over time, leading to leaks and potential contamination of the water supply. Copper, on the other hand, has natural corrosion resistance properties, making it a more durable and reliable option for plumbing systems. Additionally, copper pipes are known to have better heat conductivity and are easier to bend and shape, making them a preferred choice in plumbing installations.
