Preparation and properties Edit

Rubidium perchlorate can be obtained through the careful heating of a rubidium chlorate solution, leading to a disproportionation reaction with the release of oxygen gas:[3]

2 RbClO3 → RbClO4 + RbCl + O2

When heated, it decomposes into the chloride and oxygen:[4]

RbClO4 → RbCl + 2 O2

It has two polymorphs. Below 279 °C, it crystallizes in orthorhombic crystal system with lattice constants a = 0.927 nm, b = 0.581 nm, c = 0.753 nm. Over 279 °C, it has a cubic structure with lattice constant a = 0.770 nm.[1]
