Chemical compound

Francium hydroxide is a hypothetical inorganic compound with a chemical formula FrOH. It is a hydroxide of francium.

It probably can be produced by reacting francium metal with water:[1]

2 Fr + 2 H2O → 2 FrOH + H2 (gas)

This reaction might be explosive, because this reaction is probably very exothermic, because of which water could suddenly start boiling violently, producing hot water vapor, and very flammable hydrogen gas is produced in the reaction as well, and hydrogen could ignite, causing fire and explosion. However this is all guesswork, as a visible quantity of francium has never been made.

Francium hydroxide's alkalinity is predicted to be stronger than caesium hydroxide.[2]
