Reaction of zirconium with acids
Zirconium does not react with most acids, under normal conditions. It does dissolve in hydrofluoric acid, HF, most likely forming fluoro complexes
Reaction of zirconium with air
Zirconium does not react with air under normal conditions. If brought to burn, zirconium will react with oxygen, O2.
Zr(s) + O2(g) ZrO2(s)
Reaction of zirconium with bases
Zirconium does not appear to react wih alkalis, under normal conditions.
Reaction of zirconium with halogens
Zirconium reacts with halogens, when heated, forming the corresponding zirconium(IV) halides.
Zr(s) + 2 F2(g) ZrF4(s) [white]
Zr(s) + 2 Cl2(g) ZrCl4(s) [white]
Zr(s) + 2 Br2(g) ZrBr4(s) [white]
Zr(s) + 2 I2(g) ZrI4(s) [white]
Reaction of zirconium with water
Zirconium does not reacts with water, under normal conditions.
