Praseodymium bromate

Praseodymium bromide is an inorganic compound with the chemical formula Pr(BrO3)3. It is soluble in water and can form the dihydrate, tetrahydrate[1] and nonahydrate. The nonahydrate melts in its own crystal water at 56.5 °C and completely loses its crystal water at 130 °C.[2] It can be produced by the reaction of barium bromate and praseodymium sulfate.[3]
