Quick Reference

A compound formed in solution when beryllium metal, or the oxide or hydroxide, dissolves in strong alkali. The reaction (for the metal) is often written Be+2OH(aq) → BeO22−(aq)+H2(g) The ion BeO22− is the beryllate ion. In fact, as with the aluminates, the ions present are probably hydroxy ions of the type Be(OH)42− (the tetrahydroxoberyllate(II) ion) together with polymeric ions.

Be+2OH(aq) → BeO22−(aq)+H2(g)
