Chemical reactions of the elements Reaction of gadolinium with airGadolinium metal tarnishes slowly in air and burns readily to form gadolinium (III) oxide, Gd2O3. 4Gd + 3O2 → 2Gd2O3 Reaction of gadolinium with waterThe silvery white metal gadolinium is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form gadolinium hydroxide, Gd(OH)3, and hydrogen gas (H2). 2Gd(s) + 6H2O(g) → 2Gd(OH)3(aq) + 3H2(g) Reaction of gadolinium with the halogensGadolinium metal reacts with all the halogens to form gadolinium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively gadolinium(III) bromide, GdF3, gadolinium(III) chloride, GdCl3, gadolinium(III) bromide, GdBr3, and gadolinium(III) iodide, GdI3. 2Gd(s) + 3F2(g) → 2GdF3(s) [white] 2Gd(s) + 3Cl2(g) → 2GdCl3(s) [white] 2Gd(s) + 3Br2(g) → 2GdBr3(s) [white] 2Gd(s) + 3I2(g) → 2GdI3(s) [yellow] Reaction of gadolinium with acidsGadolinium metal dissolves readily in dilute sulphuric acid to form solutions containing the colourless aquated Gd(III) ion together with hydrogen gas, H2. It is quite likely that Gd3+(aq) exists as largely the complex ion [Gd(OH2)9]3+ 2Gd(s) + 3H2SO4(aq) → 2Gd3+(aq) + 3SO42-(aq) + 3H2(g) Reaction of gadolinium with basesWebElements ShopWebElements now has an online shop at which you can buy periodic table posters, mugs, T-shirts, games, molecular models, and more.
