Metal-Water Reactions Chemistry Tutorial
Why would you not use a metal such as magnesium to make water pipes? Response: Magnesium is a more active metal than copper. Magnesuim would react with the water in the pipes to produce magnesium hydroxide which would produce "hard water" (soap won''t lather properly in hard water), causing the magnesium pipe to disintegrate over time.
