Chemical reactions of the elementsReaction of zirconium with airZirconium metal is coated with an oxide layer that usually renders it inactive. However zirconium does burn in air if provoked to form thedioxide zirconium(IV) oxide, ZrO2. Zr(s) + O2(g) → ZrO2(s) Reaction of zirconium with waterZirconium does not react with water under normal conditions. Reaction of zirconium with the halogensZirconium does react with the halogens upon warming to form zirconium(IV) halides. So, zirconium reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively zirconium(IV) bromide, ZrF4, zirconium(IV) chloride, ZrCl4, zirconium(IV) bromide, ZrBr4, and zirconium(IV) iodide, ZrI4. Zr(s) + 2F2(g) → ZrF4(s) [white] Zr(s) + 2Cl2(g) → ZrCl4(l) [white] Zr(s) + 2Br2(g) → ZrBr4(s) [white] Zr(s) + 2I2(g) → ZrI4(s) [white] Reaction of zirconium with acidsZirconium metal is coated with an oxide layer that usually renders it inactive. Most cold mineral acids have little effect. Zirconium does dissolve in hydrofluoric acid, HF, presumably to form fluoro complexes. Reaction of zirconium with basesZirconium does not appear to react wih alkalis under normal conditions, even when hot.
