Praseodymium(III) acetate is an inorganic salt composed of a Praseodymium atom trication and three acetate groups as anions. This compound commonly forms the dihydrate, Pr(O2C2H3)3·2H2O.[2]
Preparation
Praseodymium(III) acetate can be formed by the reaction of acetic acid and praseodymium(III) oxide:[3]
- [math]\displaystyle{ \mathsf{6CH_3COOH + Pr_2O_3 \ \xrightarrow{T}\ 2Pr(CH_3COO)_3 + 3H_2O} }[/math]
Praseodymium(III) carbonate and praseodymium(III) hydroxide can also be used:
- [math]\displaystyle{ \mathsf{6CH_3COOH + Pr_2(CO_3)_3 \ \xrightarrow{T}\ 2Pr(CH_3COO)_3 + 3H_2O + 3CO_2} }[/math]↑
- [math]\displaystyle{ \mathsf{6CH_3COOH + 2Pr(OH)_3 \ \xrightarrow{T}\ 2Pr(CH_3COO)_3 + 6H_2O} }[/math]
Decomposition
When the dihydrate is heated, it decomposes to the anhydrous, which then decomposes into praseodymium(III) oxyacetate(PrO(O2C2H3)) then to praseodymium(III) oxycarbonate, and at last to praseodymium(III) oxide.[2]
