24/9/2006· Metals such as pluum, copper, silver and gold do not react with water at all disregarding whether it is of cold water or steam. This can be understood by analyzing the oxdation series. The higher the position of the metal in the oxidation series, the easier it reacts with water or other compounds.

Reaction of zinc metal with water: Zinc metal produces zinc oxide and hydrogen gas when steam is passed over it. Zinc does not react with cold water. Zn + H 2 O ZnO + H 2 Reaction of Iron with water: Reaction of iron with cold water is very slow and come into notice after a long time.
Hard Water and How It Damages Pluing - The Spruce
How Does Water Become Hard? Although rainwater is pure when it falls from the sky, as it flows from the surface into aquifers, it absorbs minerals, primarily calcium and magnesium. This absorption changes it from soft to hard water. The amount of mineral content
