Praseodymium(III) iodate is an inorganic compound with the chemical formula Pr(IO3)3.
Preparation
[edit]Praseodymium(III) iodate can be obtained by reacting praseodymium(III) nitrate and potassium iodate in a hot aqueous solution:[2]
- Pr(NO3)3 + 3 KIO3 → Pr(IO3)3 + 3 KNO3
Properties
[edit]Praseodymium(III) iodate can be thermally decomposed as follows:[3]
- 7 Pr(IO3)3 → Pr5(IO6)3 + Pr2O3 + 9 I2 + 21 O2
