Rubidium hydride is a chemical compound. It contains rubidium and hydride ions. Its chemical formula is RbH. It is a strong reducing agent and will react with water, air and chlorine violently. It is made by disproportionating hydrogen by reacting hydrogen with rubidium hydroxide. This process also produces rubidium oxide. It is normally made by reacting rubidium and hydrogen.
