Galvanized chemistry
WebGalvanized iron is iron coated with a thick layer of zinc. The zinc layer prevents the iron from corroding. In this experiment, we will remove the zinc layer by dissolving it in … In the early 20th century, galvanized piping replaced previously-used cast iron and lead in cold-water plumbing. Typically, galvanized piping rusts from the inside out, building up layers of plaque on the inside of the piping, causing both water pressure problems and eventual pipe failure. These plaques can flake off, leading to visible impurities in water and a slight metallic taste. The life expectancy of galvanized piping is about 40–50 years, but it may vary on how well the pipes we…
