'''Beryllium hydroxide''' is one of the few [[amphoteric]] metal [[hydroxides]], capable of being an [[acid]] or a [[base (chemistry)|base]] under different conditions.[http://www.atsdr.cdc.gov/toxprofiles/tp4-c4.pdf] For example, it dissolves in [[sodium hydroxide]] solution to give a colourless solution of sodium [[beryllate]]:
2NaOH(aq) + Be(OH)<sub>2</sub>(s) → Na<sub>2</sub>Be(OH)<sub>4</sub>(aq)
With acids, beryllium hydroxide acts as a typical base, and beryllium salts are formed.
