  2. Zinc - Wikipedia

    en.wikipedia.org/wiki/Zinc

    Zinc is more reactive than iron or steel and thus will attract almost all local oxidation until it completely corrodes away. [124] A protective surface layer of oxide and carbonate (Zn 5 (OH) 6 (CO 3) 2) forms as the zinc corrodes. [125] This protection lasts even after the zinc layer is scratched but degrades through time as the zinc corrodes ...

  3. Group 12 element - Wikipedia

    en.wikipedia.org/wiki/Group_12_element

    Zinc, cadmium and mercury form a large range of alloys. Among the zinc containing ones, brass is an alloy of zinc and copper. Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium and sodium. [11]

  4. Zinc compounds - Wikipedia

    en.wikipedia.org/wiki/Zinc_compounds

    Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...

  5. Hot-dip galvanization - Wikipedia

    en.wikipedia.org/wiki/Hot-dip_galvanization

    Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F).

  6. Zinc oxide - Wikipedia

    en.wikipedia.org/wiki/Zinc_oxide

    Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...

  7. Metal ions in aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Metal_ions_in_aqueous_solution

    For example, comparing the potentials for zinc (-0.75 V) with those of iron (Fe(II) -0.47 V, Fe(III) -0.06 V) it is seen that iron ions are more easily reduced than zinc ions. This is the basis for using zinc to provide anodic protection for large structures made of iron or to protect small structures by galvanization.
