WebWith acids, beryllium salts are formed. For example, with sulfuric acid, H 2 SO 4, beryllium sulfate is formed: Be(OH) 2 + H 2 SO 4 → BeSO 4 + 2 H 2 O. Beryllium hydroxide dehydrates at 400 °C to form the soluble white powder, beryllium oxide: Be(OH) 2 → BeO + H 2 O. Further heating at higher temperature produces acid insoluble BeO. References
