Rubidium perchlorate

Rubidium perchlorate, RbClO4, is the perchlorate of rubidium. It is an oxidizing agent, as are all perchlorates.

Preparation and properties
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:


 * 2 RbClO3 → RbClO4 + RbCl + O2

When heated, it decomposes into the chloride and oxygen:


 * 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.
