'''Francium hydroxide''' is a [hypothetical](/source/hypothetical_chemical_compound) [inorganic compound](/source/inorganic_compound) with a [chemical formula](/source/chemical_formula) {{chem2|FrOH|auto=1}}. It is a [hydroxide](/source/hydroxide) of [francium](/source/francium).

It probably can be produced by reacting francium metal with [water](/source/water):<ref name="idk">{{citation|title=The History and Use of Our Earth's Chemical Elements: A Reference Guide |page= 64|author=Robert Krebs|publisher=Robert Krebs|isbn=0313334382|chapter-url={{Google Books|yb9xTj72vNAC|page=64|link=tak|plainurl=yes}}|language=en|chapter=Francium|year= 2006}}</ref>
:{{chem2|2 Fr + 2 H2O → 2 FrOH + H2([gas](/source/gas))}}
This reaction might be explosive, because this reaction is probably very [exothermic](/source/exothermic), because of which [water](/source/water) could suddenly start [boiling](/source/boiling) violently, producing hot [water vapor](/source/water_vapor), and very flammable [hydrogen](/source/hydrogen) gas is produced in the reaction as well, and hydrogen could ignite, causing fire and explosion. However this is all guesswork, since a visible quantity of francium has never been made.

Francium hydroxide's [alkalinity](/source/alkalinity) is predicted to be stronger than [caesium hydroxide](/source/caesium_hydroxide).<ref name="idk2">Douglas Considine, Glenn Considine: ''Van Nostrand’s Scientific Encyclopedia.'', {{ISBN|978-1-4757-6920-3}}, s.&nbsp; 605</ref>
