Lanthanum (III) oxalate is an inorganic compound, a metal salt of lanthanum and oxalic acid with the formula La ₂ (C ₂ O ₄ ) ₃ , colorless crystals insoluble in water form crystalline hydrates .

Getting

Effect on soluble lanthanum salts with an excess of oxalic acid:

{\mathsf {2La(NO_{3})_{3}+3(COOH)_{2}\ {\xrightarrow {}}\ La_{2}(C_{2}O_{4})_{3}\downarrow +6HNO_{3}}}

{\ displaystyle {\ mathsf {2La (NO_ {3}) _ {3} +3 (COOH) _ {2} \ {\ xrightarrow {}} \ La_ {2} (C_ {2} O_ {4}) _ {3} \ downarrow + 6HNO_ {3}}}}

Physical Properties

Lanthanum (III) oxalate forms colorless crystals, poorly soluble in water.

It forms crystalline hydrates of the composition La ₂ (C ₂ O ₄ ) ₃ • n H ₂ O, where n = 1, 2, 3, 7, and 10.

Chemical Properties

Crystalline hydrate decomposes on heating:

{\mathsf {La_{2}(C_{2}O_{4})_{3}\cdot 10H_{2}O\ {\xrightarrow[{-H_{2}O}]{80^{o}C}}\ La_{2}(C_{2}O_{4})_{3}\cdot 7H_{2}O\ {\xrightarrow[{-H_{2}O}]{80-320^{o}C}}\ La_{2}(C_{2}O_{4})_{3}\ {\xrightarrow[{-CO,-CO_{2}}]{400^{o}C}}\ La_{2}O(CO_{3})_{2}\ {\xrightarrow[{-CO_{2}}]{800^{o}C}}\ La_{2}O_{3}}}

{\ displaystyle {\ mathsf {La_ {2} (C_ {2} O_ {4}) _ {3} \ cdot 10H_ {2} O \ {\ xrightarrow [{- H_ {2} O}] {80 ^ { o} C}} \ La_ {2} (C_ {2} O_ {4}) _ {3} \ cdot 7H_ {2} O \ {\ xrightarrow [{- H_ {2} O}] {80-320 ^ {o} C}} \ La_ {2} (C_ {2} O_ {4}) _ {3} \ {\ xrightarrow [{- CO, -CO_ {2}}] {400 ^ {o} C}} \ La_ {2} O (CO_ {3}) _ {2} \ {\ xrightarrow [{- CO_ {2}}] {800 ^ {o} C}} \ La_ {2} O_ {3}}}}
