Whether we are talking about its impact on society, its relevance in history, its importance today or any other related aspect, Yttrium oxalate is a topic that never stops generating debate and discussion. From its origins to its influence on the present, Yttrium oxalate has been an object of study and interest for academics, professionals, and the general public. In this article, we will explore the various aspects related to Yttrium oxalate and try to shed light on this topic that is so relevant today.
Yttrium oxalate is an inorganic compound, a salt of yttrium and oxalic acid with the chemical formula Y2(C2O4)3. The compound does not dissolve in water and forms crystalline hydrates—colorless crystals.
Synthesis
Precipitation of soluble yttrium salts with oxalic acid:
Properties
Yttrium oxalate is highly insoluble in water and converts to the oxide when heated. Yttrium oxalate forms crystalline hydrates (colorless crystals) with the formula Y2(C2O4)3•n H2O, where n = 4, 9, and 10.
Decomposes when heated:
The solubility product of yttrium oxalate at 25 °C is 5.1 × 10−30.
The trihydrate Y2(C2O4)3•3H2O is formed by heating more hydrated varieties at 110 °C.
Y2(C2O4)3•2H2O, which is formed by heating the decahydrate at 210 °C) forms monoclinic crystals with unit cell dimensions a=9.3811 Å, b=11.638 Å, c=5.9726 Å, β=96.079°.
