Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
- 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.
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
When heated, yttrium(III) hydroxide will decompose:
- 2 Y(OH)3 → Y2O3 + 3 H2O↑
