Rubidium hydrazoate, RbN₃

The Rubidium hydrazoate, RbN₃, is produced by the interaction of rubidium sulphate and barium hydrazoate. It forms tetragonal plates melting at 330° to 340° C., which display marked double refraction. It is not very explosive, but melts between 330° and 340° C. with evolution of gas. The solubility at 16° C. is 107.1 grams in 100 grams of water, the solution having a slightly alkaline reaction.
