10 Uses of Rubidium in Everyday Life

The method used to extract rubidium is by using the reduction method the rubidium metal is prepared by reducing the melt of the RbCl compound according to the reaction Na + RbCl - Rb + NaCl This reaction is in equilibrium Because Rubidium is volatile rubidium can be produced continuously in the same way as a potassium reduction process
