Chemical reactions of the elementsReaction of scandium with airScandium metal tarnishes in air and burns readily to form scandium (III) oxide, Sc2O3. 4Sc + 3O2 Reaction of scandium with waterWhen finely divided, or heated, scandium metal dissolves in water to form solutions containing the aquated Sc(III) ion together with hydrogen gas, H2. 2Sc(s) + 6H2O(aq) Reaction of scandium with the halogensScandium is very reactive towards the halogens fluorine, F2, chlorine, Cl2 bromine, Br2, and iodine, I2, and burns to form the trihalides scandium(III) fluoride, ScF3 , scandium(III) chloride, ScCl3, scandium(III) bromide, ScBr3, and scandium(III) iodide, ScI3 respectively. 2Sc(s) + 3F2(g) 2Sc(s) + 3Cl2(g) 2Sc(s) + 3Br2(g) 2Sc(s) + 3I2(g) Reaction of scandium with acidsScandium metal dissolves readily in dilute hydrochloric acid to form solutions containing the aquated Sc(III) ion together with hydrogen gas, H2. 2Sc(s) + 6HCl(aq) Reaction of scandium with bases |
