Yttrium(III) hydroxide is an inorganic compound and an alkali with the chemical formula Y(OH)3.


Production

Yttrium(III) hydroxide can be produced by reacting yttrium(III) nitrate and sodium hydroxide in aqueous solution:田俐，陈稳纯，陈琳 等. 水热法合成氢氧化钇纳米管. 无机材料学报. 2009. 24(2): 335-339 : Y(NO3)3 + 3 NaOH → Y(OH)3↓ + 3 NaNO3 This gives yttrium(III) hydroxide as a white gelatinous precipitate, which can be dried to a white powder.


Chemical properties

Yttrium(III) hydroxide is an alkali, so it can react with acid: : Y(OH)3 + 3 HNO3 → Y(NO3)3 + 3 H2O : 2 Y(OH)3 + 3 H2SO4 → Y2(SO4)3 + 3 H2O The compound absorbs atmospheric
carbon dioxide Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is trans ...
. When heated, yttrium(III) hydroxide will decompose: : 2 Y(OH)3 → Y2O3 + 3 H2O↑
